i'd vote against it if i meant that i'd continually lose trying to use
my "other" 5 gig ide drive in my old computer where i *don't* want to
write the disklabel to disk but just shove one "in-core".  if the
kernel loses the disklabel after the last "close", then i'll
continually be stuffing it in-kernel and then losing it; never getting
to mount the disk.
