Not so fast:
22 + 1.06 + 5.76 + 15 + 5.22 + .95 = 49.99 MB.
Seems that FreeBSD may have even added a few SIMMS in there. This OS is

See top(1) for a really useful description:
Active:

Inact: number of pages inactive
Wired: number of pages wired down
Hmmm, I wouldn't have thought so. They anyway show K or M, not # of
