Actually, from glibc source there's a hook that is supposed to do this in
some circumstances. Never could actually make it work in real life. Also,
IIRC glibc on Linux allocates really large (8k+? 16k+?) blocks as mmap's
of /dev/zero and those are really given back to system, since on free they
are just munmap'ed.
