This would indicate increase in RSS does not necessarily mean
unstableness you originally observed with repetitive invocations of
VM.  It would be worth trying the X11 build to see its behavior is
much like the NS port with graphical frame case (crash in GC?) or tty
case (stable).

Do you mean RSS continues to increase on each invocation of VM?  What
do the outputs of the `heap' command look like before and after an
invocation of VM at this stage?  If you find increase in malloced
memory in these outputs, then can you identify the stack traces for
some major differences using `malloc_history'?
