shutdown procedures (which have a duration of more than 120 seconds).
We have two user-space affecting shutdown timeouts: a "soft" one in
/etc/rc.shutdown and a "hard" one in init(8). The first one can be
configured via /etc/rc.conf variable "rcshutdown_timeout" and defaults
to 30 seconds. The second one was originally (in 1998) intended to be
configured via sysctl(8) variable "kern.shutdown_timeout" and defaults
to 120 seconds.
Unfortunately, the "kern.shutdown_timeout" was declared "unused" in 1999
(as it obviously is actually not used within the kernel itself) and
hence was intentionally but misleadingly removed in revision 1.107 from
init_main.c. Kernel sysctl(8) variables are certainly a wrong way to
control user-space processes in general, but in this particular case the
sysctl(8) variable should have remained as it supports init(8), which
isn't passed command line flags (which in turn could have been set via
/etc/rc.conf), etc.
As there is already a similar "kern.init_path" sysctl(8) variable which
directly affects init(8), resurrect the init(8) shutdown timeout under
sysctl(8) variable "kern.init_shutdown_timeout". But this time document
it as being intentionally unused within the kernel and used by init(8).
Also document it in the manpages init(8) and rc.conf(5).

- Replace 'process' with 'thread' everywhere.
- Update several places to note that that the fact that default mutexes
may adaptively spin isn't necessarily MD, but is just part of the
implementation as a whole.
- Clarify the text about MTX_SPIN mutexes only being appropriate for
INTR_FAST interrupts or other low level scheduler code to make the
jargon more FreeBSD-ish rather than BSD/OS-ish.
- Also, note that it is possible that interrupts aren't blocked but just
deferred when a spin lock is held (the whole blocked vs. deferred bit is
an MD implementation detail).
- Remove statements saying that spin locks must be released in the exact
opposite order that they were acquired. This stopped being true several
years ago when we first added critical sections that stored their state
in the current thread rather than in struct mtx.
- Note that a mutex must be initialized before it is passed to any other
mutex function, not just mtx_lock.
- Clarify that mtx_trylock() only operates on MTX_DEF mutexes.
- Simplify the text about possible preemption during a mtx_unlock().
- Use complete English sentences in place of phrases in a few places.
- Clarify that it isn't ever safe to sleep with a mutex held. The kernel
tends to panic when you do that.

ports trees up to date.
This is version 0.9.4 from the ports tree (sysutils/portsnap) with
the following changes:
1. The experimental pipelined http code is enabled. No seatbelts
in -CURRENT. (^_^)
2. The working directory has moved from /usr/local/portsnap to
/var/db/portsnap (as discussed on -arch two days ago).
3. Portsnap now fetches a list of mirrors (distributed as DNS SRV
records) and selects one randomly. This should help to avoid the
uneven loading which plagues the cvsup mirror network.
4. The license is now 2-clause BSD instead of 3-clause BSD.
5. Various incidental changes to make portsnap fit into the base
system's build mechanics.

- documented in UPDATING and build(7)
The head of the file ObsoleteFiles.inc contains instructions how to add
obsolete files/dirs/libs to the list. Obviously one should add obsolete
files to this list, when he removes a file/dir/lib from the basesystem.
Additionally add check-old target:
- allows re@ to check if a file on the obsolete list resurfaces
Design goals:
- allows full control by the user (default interactive mode)
- possibility of scripted removal of obsolete files (batch mode)
- opt-in removal of files (explicit list of files)
- seperate removal of libs (2 delete targets)
Important design decissions:
- structured list of files to remove instead of a plain text file:
* allows to remove additional files if a NO_foo knob is specified
without the need to change the targets (no NO_foo knob is respected
yet)
- not using mtree like NetBSD does:
* mtree doesn't has an interactive mode

struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.
This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.
Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address
from driver private storage rather than sometimes being ac_enaddr.
