- 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.

- The first "alias" "Yes" should be "No**".
- Made "builtin echo command" consistent with csh and sh manpages.
- In group of 3 interactive commands, 2 used .Pa instead of .Ic.
- "Name" section now has "builtin" and "built-in" for better apropos.
- Added these builtins: !, %, ., :, @, {, }, local, return

Explain why -M is good for these file systems (it maximizes
performance and makes the system more stable at low memory
conditions by reducing the chance of thrashing.)

of the form "REFUSE foo" in portsnap.conf will result in parts of the
tree matching "^foo" being (a) not extracted by "portsnap extract", (b)
not updated by "portsnap update", and (c) not having any patches or new
ports downloaded by "portsnap fetch" or "portsnap cron". The example
shown in portsnap.conf demonstrates ignoring all the language categories.
As mentioned in portsnap.conf.5, the use of an imcomplete ports tree is
not officially supported; but this is something which many users have
requested, so I'm adding it anyway.

- Add a new ifconfig_<ifn> keyword, NOAUTO which prevents configuration
of an interface at boot or via /etc/pccard_ether. This allows
/etc/rc.d/netif to be used to start and stop an interface on a purely
manual basis. The decision to affect pccard_ether may be revisited at
a later date.
