The offical line is that ``we're'' removing it entirely.  The ARI says 
``GDB is trying to eliminate the [x]mmalloc() family.'' so it must be 
true ... :-^

(No I don't remember exactly when this was discusssed.  Its' one of 
those things that was drummed into me from long long ago :-)

It would mean that GDB could no longer be compiled to pull the ``use 
mmap to save sections trick'' but I gather from the discussion (I don't 
remember) that this was acceptable.
