After an initial stab at modifying the source code to ignore peer
configuration differences, I decided that the impact of resetting the
bloom filters was so benign that it wasn't worth adding more complexity
to the code.  I raised the filter_bits to 25 with a clean statefile late
on Friday.  No problems resulted from this.

This seems to have solved the false positive issue for those campus MTAs
that were always at the top of the list.  Although, the match rate
didn't seem to change (still at 4-6%,) which I was hoping would go lower.
