Why is "not returning memory to the OS" a "problem"?  Whether or when
freed memory is returned to the system is up to the implementation of
the malloc library and not something applications should care about in
general.

I don't think the experiment like in

  http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00561.html

makes much sense.  What is more important is to identify whether the
crash "problem" you see with VM is caused by "not returning memory to
the OS" or other reasons.  Did you try the procedure I mentioned
earlier?

  http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00552.html

You should compare the addresses in heap between the second and the
third invocations for example, rather then one between before and
after the first invocation.
