find_blocks() performance degradation

[mpenning]

I only see around an 18-fold difference vs the reported 30-fold difference, but I can improve the speed in find_blocks() pretty easily.

This compares 0.9.24 (where you filed Github Issue #1... I'll call it an enhancement request), with the find_blocks() changes in 0.9.25 (which has the performance enhancement)
