The UW-IMAP server was actually designed to use this "feature" as a
means of deleting messages from a mailbox folder.  Whenever someone
deleted files from their inbox, uw-imap would copy the entire folder
to /tmp, open the file, delete the file, then slowly begin copying all
the *non-deleted* messages back the the inbox folder.

Aside from being slow, this also caused lots of problems with users
who had messages which contained huge Office docs!  You really needed
a large /tmp space on your mail server :)
