__setjmp, __longjmp, __sigsetjmp, and __siglongjmp, respectively.
This supports cancellation in the linuxthreads port. In the long run,
a much more comprehensive solution will necessitate more dramatic changes
to libc symbol naming, and these aliases will probably need modification
at that time.
MAN8+= rstat_svc.8
The file it talks about doesn't exist on FreeBSD, so there's no point in
installing the manual page. There was already a comment to this effect in
this file, but the entry hadn't been commented out.
rstat.1 and rstat_svc.8 can probably actually be removed.

madvise().
This feature prevents the update daemon from gratuitously flushing
dirty pages associated with a mapped file-backed region of memory. The
system pager will still page the memory as necessary and the VM system
will still be fully coherent with the filesystem. Modifications made
by other means to the same area of memory, for example by write(), are
unaffected. The feature works on a page-granularity basis.
MAP_NOSYNC allows one to use mmap() to share memory between processes
without incuring any significant filesystem overhead, putting it in
the same performance category as SysV Shared memory and anonymous memory.

is good for... :-)), I discovered that part of the change when mkstemps()
was brought in was missed - it was missing the termination case to make
sure it doesn't walk into the suffix. This isn't the same code OpenBSD
has, I think this is a little better as we terminate the loop in a better
spot.
Discuss in the BUGS section of the manpage, problems involved with
the use of %C, %e, %l, %p, %U and %W.

Before this change, a signal was delivered to each thread that
didn't have the signal masked. Signals also improperly woke up
threads waiting on I/O. With this change, signals are now
handled in the following way:
o If a thread is waiting in a sigwait for the signal,
then the thread is woken up.
o If no threads are sigwait'ing on the signal and a
thread is in a sigsuspend waiting for the signal,
then the thread is woken up.
o In the case that no threads are waiting or suspended
on the signal, then the signal is delivered to the
first thread we find that has the signal unmasked.
o If no threads are waiting or suspended on the signal,
and no threads have the signal unmasked, then the signal
is added to the process wide pending signal set. The
signal will be delivered to the first thread that unmasks
the signal.
If there is an installed signal handler, it is only invoked
if the chosen thread was not in a sigwait.
In the case that multiple threads are waiting or suspended
on a signal, or multiple threads have the signal unmasked,
we wake up/deliver the signal to the first thread we find.
The above rules still apply.

the environment. This allows big ID warnings to be suppressed for
vipw and chpass as well.
Since the environment variable test is only performed for callers
of pw_scan() that do not set pw_big_ids_warning, the test can still
be overriden. Currently, chpass and pwd_mkdb are the only users
of pw_scan() and neither of them overrides the environment variable
test.
NGM_BINARY2ASCII, which convert control messages to ASCII and back.
This allows control messages to be sent and received in ASCII form
using ngctl(8), which makes ngctl a lot more useful.
This also allows all the type-specific debugging code in libnetgraph
to go away -- instead, we just ask the node itself to do the ASCII
translation for us.
Currently, all generic control messages are supported, as well as
messages associated with the following node types: async, cisco,
ksocket, and ppp.
See /usr/share/examples/netgraph/ngctl for an example of using this.
Also give ngctl(8) the ability to print out incoming data and
control messages at any time. Eventually nghook(8) may be subsumed.
Several other misc. bug fixes.
