to get a stacktrace. This does not work even with M_NOWAIT when we
have WITNESS and is generally a bad idea (pointed out by bde@). We
allocate an 8K heap for use by the unwinder when ddb is active. A
stack trace roughly takes up half of that in any case, so we have
some room for complex unwind situations. We don't want to waste too
much space though. Due to the nature of unwinding, we don't worry
too much about fragmentation or performance of unwinding while in
the debugger. For now we have our own heap management, but we may
be able to leverage from existing code at some later time.
While here:
o Make sure we actually free the unwind environment after unwinding.
This fixes a memory leak.
o Replace Doug's license with mine in unwind.c and unwind.h. Both
files don't have much, if any, of Doug's code left since the EPC
syscall overhaul and the import of the unwinder.
o Remove dead code.
o Replace M_NOWAIT with M_WAITOK for all remaining malloc() calls.

fragment resulted in two vertical spaces. From ChangeLog:
2003-07-04 Ruslan Ermilov <ru@FreeBSD.org>
* tmac/doc.tmac (Bd): Change to doc-Li-font later.
- Removed dead declarations
- Made objects that should have been declared as static, static.
The changes use STATIC instead of static, following the existing
convention in the rest of the code.

by sizeof(wchar_t) to get the number of wide characters it contains.
Remove the !hardway micro-optimisation from the CT_INT case to avoid
having to fix it for wide characters.
notice another typo in the same line. This typo makes libthr unuseable,
but it's effects where counter-balanced by the extra semicolon, which
made libthr remarkably useable for the past several months.
Should work with both regular and fast ipsec (mutually exclusive).
See manpage for more details.

- Associate logical CPUs on the same physical core with the same kseq.
- Adjust code that assumed there would only be one running thread in any
kseq.
- Wrap the HTT code with a ULE_HTT_EXPERIMENTAL ifdef. This is a start
towards HyperThreading support but it isn't quite there yet.

comprised of the path to a make(1) binary (possibly the one
built by the "make" target in this Makefile), and a path to
a fresh share/mk. The idea is to allow "make release" pick
up the right "make" binary, if one exists.
This fixes release.5 I broke with the last commit here; the
second PATH here was overriding the right one from WMAKEENV
while rebuilding the "build-tools" for crunched binaries.
BUS_DMA_NOWAIT flag, since the code can't handle this.
- Use NULL, NULL for the lockfunc and lockfuncarg parameters of
bus_dma_tag_create() since deferred loads can't happen now.
as the target process' pid, it may exist if the process forked before leaving
the pgrp.
Thix fixes a panic that happens when calling setpgid to make a process
re-enter the pgrp with the same pgid as its pid if the pgrp still exists.
