Jason said that his reply wasn't supposed to go to the list, but after
reading it I realized that "basic allocator" may be how should I put it
somewhat "underspecified".

What I meant to say was that a moving collector could probably reuse
part or all of the allocator in mem/.  Plus, it may also use the existing
scheme for deciding whether a given value is a pointer to a gcable object
or just looks like one.  That's all I meant to say.
