spam.el is a bit aggressive loading/saving spam-stat data

[David Z Maze <dmaze@MIT.EDU>]

spam.el with spam-stat seems to work fairly well for me (certainly, as
well as ifile ever did).  The one thing I was hoping for out of it,
though, was that since the scoring information lived with the Emacs
process, I wouldn't take a performance hit for reading and parsing a
500K text file for every incoming message.  The code in spam.el seems
to be on the aggressive side loading and saving, though: spam-split,
which is called for every message, calls (spam-stat-load), and both of
the spam-stat-register functions end by calling (spam-stat-save).

Is it straightforward to change this so that (spam-stat-load) happens
once when Gnus starts up, and then (spam-stat-save) is called, say,
along with everything else when I press 's' from the group buffer?
I'd think this would noticably improve splitting performance for me.

Thanks,
