Well, I think it's a band-aid until we can redesign the memory manager
properly, but it could be a useful band-aid ... might as well put it in.

The only thing that bothers me about the code itself is lack of
comments.  In particular it'd be nice to mention somewhere that freeptr
is actually one chunkheader past the start of the free space --- took
a while to puzzle that out.
