I retrain on my entire saved email collection periodically.  After a full
retrain, I delete all hapaxes (well, I copy the database except for the
hapaxes it contains).  It cuts the database size roughly in half, and if,
after adding more messages, those tokens are no longer hapaxes, they will be
kept after the next retrain.

Seems to work for me.
