I wouldn't use short-circuiting on a home computer, unless it
really can't cope with the throughput and even then I'd start by
short-circuiting ham. If you want to place more reliance on BAYES then
change it's scores. 

If you short-circuit on BAYES_99 you lose the benefit of negative
scoring rules. You also lose one of SA's best features: the ability to
distinguish between certain spam and probable spam, and that makes it
much harder to spot any FPs.
