the nullfs code doesn't allow one to remount a filesystem and change
the read-write / read-only mode. one is forced to unmount and remount,
which means it can't be done on an active filesystem.
mount /usr/src as read-only nullfs. after you've finished a build and
want to modify sources, attempt to mount -u -o rw /usr/src and fail.
write the code to support this in nullfs. i had a look but i'm going
to leave this one to someone else....
