Factory should handle os.fork() failing
The GOC saw os.fork() fail because no more memory could be allocated.
If this happens, we should catch the OSError and do something.
(It would be good to figure out why it happened, too.)

Parag had the same comment, but I think fork failing should be fatal -- we really can't do useful work at that point and the machine
is nearly out of memory.
Remember that the factory will restart the entryGroup when it exits, so the factory will keep chugging along. And restarting
the entryGroup should defragment the memory too (if that's what causes the PSS to increase over time).
