many mbufs). Somewhat needed for the rl(4) fix to ensure that the ethernet
header is in one mbuf for sure. Tested by landry@ and myself

got multiple signals before tsleep() could wakeup. Also, POSIX
says that sigwait() should never return EINTR, so map that to
ERESTART.

VA_EXCLUSIVE. Handle this in NFS, also in NFS use arc4random()
for the create verifier instead of an uninitialized long and
the address of the first interface (which is likely to be lo0).

non-private key and flags of IPC_CREAT.
Before, if we found an existing semaphore, we jumped to the return and
forgot the free the preallocated semaphore. Instead, free it before we
jump.

write buffer, not the amount of space used. It is debatable wether the
size of the write buffer is set by the size of the buffer or the high water
mark. For now, go with the former since that seems to be more consistent
with what the pipe and socet code does. It is also what NetBSD does.

that takes an additional argument "type" that indicates whether the
signal is for the process, just a particular thread, or propagated
to a thread because it's not caught or blocked. psignal() becomes
a wrapper that does the first of those.
So that sys_kill() can tell apart signals for the process and signals
for the process's original thread, the tid of the original thread
is defined as its pid + THREAD_PID_OFFSET.

drivers are guaranteed to make progress. We could probably set it to 1,
but we set it to 2, to make sure drivers that link descriptors don't link
a descriptor back to itself.
