Hey Daniel, I am no GC expert but I'm liking this a lot.  I love the
block comments in your alloc.c -- very clear and easy to understand.
You're in a uniquely good position to work on this.  I hope you
continue!

I'm curious about the answer to one of the unanswered questions in your
alloc.c FAQ: What about systems without virtual memory?  Asked another
way: can we reasonably expect to entirely replace the current GC with
this new one?  Are there platforms Emacs supports today that would be
left behind?
