Now, you can just blow /usr/obj out without any ill efects. Whenever I do
my regular stable buildworld on Saturdays, I start like this:

cd /usr/obj
chflags -R noschg *
rm -R *

The second command unsets the (system) immutable flag for everything in
/usr/obj. Otherwise, files in there might refuse to be deleted. Next, with
the rm -R command, you totally wipe out /usr/obj. Now you can change to
/usr/src, then start your make buildworld, and everything under /usr/obj
will be recreated again.

You may either want to wipe out /usr/obj *after* each make installworld
(especially if you have little HD space), or you might leave it untouched
*until* you start your next buildworld.
