I've developed a patch which implements such a mechanism and would
like it to be committed to the trunk.

Briefly: it costs one additional pointer per each memory chunk
allocated. Plus it costs thee additional pointers per allocation, if
allocation is made from pool in chunk mode when destructor is used,
otherwise it costs nothing. Callback is supplied as a parameter to
allocation function.

I would gladly read you comments, critics and suggestions regarding this patch.
