Hrm. I'll have to add some more logic then -- we want to be able to
completely clean the heap, but not advance the "free mem starts here"
pointer. What would be the right behavior: doing a full sweep, or a
mark + full sweep? Or maybe just both (first the full sweep, if it
doesn't yield enough: the full mark.)
Do you know where that function is? I can't seem to find how a new
port is added. Oh wait. This goes through scm_must_malloc. Ok.
