What's left in longdrop includes svnserve, postgres, mysql, screen, sshd, irssi and pugs. As well as all the regulars, like syslogd, cron, et al.

Aha! No less memory consumed! So, apache2 isn't so bad, after all. It's just mapped every single bloody library on my system into one mammoth process.
A good thing that this server is using Linux-Vserver for its virtual servers. Just imagine how much memory aboched2 and Xen could use if that memory wasn't allowed to be shared between servers..
