This is great to hear.  If you do find another issue with block
frequency, please CC me on the bug report.

The testcase might be interesting to look at regardless, if you're
willing to mail it.  I don't have any clear examples of slowdowns in the
old algorithm, and I'd be interested to have a closer look at what's
going on with this one.
