20 megs wouldn't get you very far at all.  I think my mail spool alone
is over 250MB right now.  (Gotta trim that, mutt takes too long to start.)

However, it would seem to me that something is holding open a file that
is rm'd on the filesystem.  That's the only way that I can think that df
would show a capacity that wasn't true.  Is softupdates turned on for
/var?  If so, have you tried 'sync' to see if that changes the df output?

Sounds like a fine idea to me.
