broke it. By changing the type of all DESTDIR variables used
internally in Makefile.inc1, from environment to command-line
variables of the highest priority, I was able to "make world"
with success, with the command-line variable DESTDIR set.
UNIX domain socket garbage collection implementation, as that risks
holding the mutex over potentially sleeping operations (as well as
introducing some nasty lock order issues, etc). unp_gc() will hold
the lock long enough to do necessary deferal checks and set that it's
running, but then release it until it needs to reset the gc state.

# is preseedrandom still necessary?
The C code assumes that the carry bit is always kept from the previous
operation. However, the pointer indexing requires another add operation.
Thus, the carry bit from the first operation is tromped over by the
"addl" operation that ends up following it, so the "adcl" that follows
that has no effect because the carry bit is cleared before it.
The result is checksum failure on received packets.
The larger issue is that there isn't any other way of preventing the compiler
inserting arbitrary instructions between different __asm statements (and
that the commit message in revision 1.13 of in_cksum.h is wrong on
this point). From

You can't expect a sequence of volatile asm instructions to remain
perfectly consecutive. If you want consecutive output, use a single
asm. Also, GCC will perform some optimizations across a volatile
asm instruction; GCC does not "forget everything" when it encounters
a volatile asm instruction the way some other compilers do.

Also, this change also makes the ASM code much easier to read.

it could result in problems if the NFS server is killed causing nfsd

On a system with huge number of pipes, M_NOWAIT failes almost always,
because of memory fragmentation.
My fix is different than the patch proposed by Pawel Malachowski,
because in FreeBSD 5.x we cannot sleep while holding dummynet mutex
(in 4.x there is no such lock).
My fix is also ugly, but there is no easy way to prepare nice and clean fix.

We do not pass the GOT entry however as the 4th argument, because it's
not used. The _mcount() stub calls __mcount(), which does the actual

implementation of mcount(), so we define MCOUNT as empty, but have a
weak alias to _mcount() in _mcount.S.
Note that the _mcount() stub in the kernel is slightly different from
the stub in userland. This is because we do not have to worry about
nested routines in the kernel.

sufficiently specific to understand when and how it would be called.
The new wording describes the current implementation's usage (which
should be updated if other appropriate times are decided upon),
specifically that it is called only when the load operation is
deferred to keep the locking state consistent. When the operation
isn't deferred, the calling routine is assumed to have a coherent
locking world.
