wordhashes [was: time test]

[David Relson]

Gyepi,

I thought bogofilter built a wordhash for each message (using 
collect_words()) and release the wordhash (freed the memory) at the end of 
the message.  Matthias' figures indicate that the release/free is 
missing.  If this is so, we have a defect in the code.  I don't think it's 
a big deal, because bogofilter is typically called for a single 
message.  However we ought to check the code and fix the problem.
