Perhaps this is the reason behind the common observation that "Linux
freezes to a crawl when it starts swapping to disk." I was told this was
one big advantage of FreeBSD. Somehow, I'm starting to think that both
OS's have this problem, but perhaps this is less noticed under FreeBSD
due to:
1) Different paging algorithms between FreeBSD and Linux (?)
2) More Linux users use IDE; more FreeBSD users use SCSI.
