(originally on a different OS without mkstemp()), albeit somewhat
bashed and hacked into something that doesn't look too much like
the original any more. It should be upwardly compatable with
OpenBSD's mktemp(1) but does a couple of extra things.
I've taken OpenBSD's mktemp.1 man page and adapted it to suit.
leading XXX's. It could wrap an uppercase character through chars
like: [ \ ] ^ _ ` in between Z and a. The backslash and back tick
might be particularly nasty in a shell script context. Also, since
we've been using upper-case generated values for a while now, go with
the flow and use them in the pathname search rotation.

features such as DMA, Ultra DMA, and 32bit mode. This patch
might have been reported by someone else (I seem to remember
it.)
kernal page table may need to be extended. But while growing the
kernel page table (pmap_growkernel()), newly allocated kernel page
table pages are entered into every process' page directory. For
proc0, the page directory is not allocated yet, and results in a
page fault. Eventually, the machine panics with "lockmgr: not
holding exclusive lock".

it was. Add a FILE_WAIT state and queue threads waiting for a FILE
lock. Start using the sys/queue.h macros instead of the way that MIT
pthreads did it.
Add a thread name to the private thread structure and a non-POSIX
function to set this. This helps (me at least) when sending a SIGINFO
to a threaded process to get a /tmp/uthread.dump to see what the
<expletive deleted> threads are doing this time. It is nice to be
able to recognise (yes, I spell that with an 's' too) which threads
are which.
Change the FILE locking to support kernel threads when linked with
libpthread (which you haven't see yet). This requires that libc become
thread-safe and thread-aware, testing __isthreaded before attempting
to do lock/unlock calls. The impact on non-threaded programs is minor.
This change works with libc_r, so it's the best compromise.
test for __isthreaded before calling the lock/unlock functions to
try to save some performance. The _THREAD_SAFE case should become the
default, but since it tests for a global variable in libc, people won't
be able to build -current on pre-3.0 systems unless the default leaves
it out. Such is life.
