[Spambayes] SpamBayes Proxy once again getting slower

[Robert Woodhead]

This is a repeat of the problem I was having earlier.  After resetting 
the databases (using Pickle AFAICT) and training on about 200 messages, 
SpamBayes is lightning fast classifying messages.  But over a couple of 
weeks it gets slower and slower and slower, it's now taking 10+ seconds 
per email to do its classification - and Python is maxing out at 100% of 
cpu when doing it.

I have set it to not train on incoming email, not cache stuff, etc, to 
no avail.

This is on a Mac, using Thunderbayes proxy.

Any suggestions?
