I'm running on 32-bit linux 2.6, using apache 2.2.4, mod_perl 2.03,
running this site : http://announce.jpress.co.uk

A typical httpd process looks like this (as output by the smem.pl script
at http://www.contrib.andrew.cmu.edu/~bmaurer/memory/smem.pl )

VMSIZE:     136832 kb
RSS:         42236 kb total
             25796 kb shared
                64 kb private clean
             16376 kb private dirty
