patch to fix the bug

Looking a little closer, Im going to change Honza's patch a little. Since the
checks are no longer being done after each BB is processed, they serve less
purpose, and are runn just before the free_() routine. 

Moving them to the free_ routine makes more sense, and when I did that, it was
clear then that there was a duplicate check there, as well as an extra loop of
potential free()s which could never be called.  so this cleans that all up.

I'll check this in once its finishes testing this morning
