Fix from the Madusa mailing list:
http://groups.yahoo.com/group/medusa/message/333
It's clear that Medusa should not be checking for an empty buffer

there's a mystery here all the same: Python attempts to store null
strings uniquely, so it's unclear why "buf is ''" ever returned
false when buf actually was empty. *Some* string operations produce
non-unique null strings, e.g.
