Hi Oleg,

Thanks for the reply.

True.

This will not magically give you garbage collection. (Hej, we're actually
*doing* something here to make these things easy to use! ;)

Replacing the memory manager only replaces the functions called for malloc,
free, etc. Diverting them to Python will call PyMem_Malloc and PyMem_Free
instead. No change in behaviour.

It will. Having Python do the memory allocation and deallocation will not
enable reference counting for the dicts (which, BTW, libxml2 already does
based on documents).

We'd still have to do our own reference counting based on each single node
that depends on the dict. That's definitely out of scope.
