	Have you tried increasing the swap space?  As long as a single
process doesn't take more than 4MB, you should be able to do the fork().
(Increasing the swap space as an afterthought can be a pain, since you have
to back up everything (and don't forget that the backup under UA skips the
foundation set, and any file which is timestamped as being older than the
install date of the foundation set), then you re-format using the improved
diagnostic disk from osu-cis, in expert mode.

	Good Luck
