I've started calculating the delta mean as well as the number of messages
pushed into spam territory.  Just eyeballing a plot of just over 100 pairs
of (mean diff, # new spams) suggests there's a weak correlation between the
two variables.

I'll probably play with it a bit more and check the script into the contrib
section so other people can play with it.
