description:
Fix zero-day bug in mfree. Previously, code assumed that the final
entry in the block map would be used. This was true for coco but is
not necessarily true (and is not true for mc09). Slight mod removes
that implicit assumption; the code now works correctly on both platforms.


(or, of course, you might have the latest version could have found a new
bug, or one that I created with my "fix")
