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.

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

There seems to be some confusion in the syscons code as to the meaning of
the SC_KERNEL_CONSOLE flag. Its absence is sometimes interpreted to mean
"I am not the system console", and sometimes to mean "I am not the only
VGA console" (see the font loading code for an example of the latter).
Someone with better syscons fu than myself should take a closer look.
