[ale] Funny Mem Usage

[Jeff Hubbs]

I just put RH 7.1 on a machine I'm putting together, more as a test than
anything else.  It's a K6-2+/500, 512MB RAM.

Here is what top (M option - sort by memory use) says:

  1:29am  up  2:33,  5 users,  load average: 1.02, 1.02, 1.00
67 processes: 62 sleeping, 4 running, 0 zombie, 1 stopped
CPU states:  0.3% user,  0.5% system, 99.0% nice,  0.0% idle

Note that I have KDE and SETI at Home running, and nothing else of note. 
However, look at that "211924K used" business.  Is top misreporting this
somehow?  Nothing seems to justify nearly half of this RAM being taken
up, including cache.
