As far as I can see the current model fundamentally only works for
one user per process (because there is only a single range and abort IP) 

So once malloc started using it noone else could.

Since malloc is the primary user it would be pointless to ever
try it on something else.

It seems fixing that would complicate everything quite a bit --
all ranges would need to be (unlimited?) arrays.
