[Spambayes] Persisting a pickled bayes database

I can see the nice createbayes function in hammie, but I don't see any
persistence function anywhere. I do see several places where code to write a
pickled bayes database is hard coded, and I understand the PersistentBayes
thing. I might be missing something...
I've been using a simple class to handle creating and persisting my bayes
databases. I *think* this stuff should probably go somewhere, but beats me
where... classifier? doesn't make much sense there... hammie? Any ideas
Here's the class... (kinda a dumb name ;))
'''helper class for bayes databases'''
def __init__(self, db_name, useDB):
''' constructor '''
self.db_name = db_name
self.useDB = useDB
self.bayes = hammie.createbayes(db_name, useDB)
# no __del__() method, because we don't *necessarily* want to persist
'''store the bayes database'''
if not self.useDB:
fp = open(self.db_name, 'wb')
pickle.dump(self.bayes, fp, 1)
