For the remaining fcntl() operations, do acquire Giant, especially

existing KTR traces generated on powerpc, as I'm primarily interested
in kernel context (thread, syscall #, proc, etc), not the user
arguments to the system call. Some convergence would be useful here.
with doFS.sh consistently dying here because the device didn't exist
in the namespace fast enough after doing the mdconfig. But the device
did eventually show up. There have been similar complaints on mailing
lists that might boil down to this being the problem too.
This is obviously a hack, if anyone knows what might cause a delay
between mdconfig running and when the name appears in the /dev namespace
(inside a chroot-ed environment if that matters) I'd be happy to back
this out.
to subordinate make(1) invocations through MAKEFLAGS, we cannot add
CFLAGS onto the make(1) command line. This will conflict with the
individual makefiles wanting to append to it, which is not respected
when CFLAGS is given on the command line. Hence build breakage.
So, put CFLAGS in the environment instead.

This takes time and time is already in short supply.

unless we are actually using inpcb fields other than the bound port
and address. Since we hold the pcbinfo lock already, these can't
change. Defer acquiring the inpcb mutex until we have a high
chance of a match. This avoids about 120 mutex operations per UDP
broadcast packet received on one of my work systems.
