a GLib G_MALLOC_DOMAIN?

[Jeff Garzik <jgarzik pobox com>]

Does there exist in GLib a facility by which I may track memory
allocations separated into distinct, named domains?

It would be nice to have mem profiling spit out separate statistics
depending on which part of a particular program did the allocation.  (or
to get even more fancy, be able to turn on and off the profiling of
specific domains)
