[Fwd: memory usage script]

[Jim Gettys]

As many/most of you should know, the Linux/UNIX "ps" command is
*EXTREMELY* misleading on accounting for *ACTUAL* ram in use by a
process.  For example, it does not account for register windows being
used by the X server, nor sharing among processes that use the same
shared library.

Attached is a note from Tridge, pointing to a script that does a much
better job accounting to real usage.

Note that the Linux kernel has recently started doing a better job
accounting for memory usage as well (after 2.6.23-rc8-mm1).
