I can't see how this would work.  The minor heap is a fixed size (32K
or something) and when this is used up, you _have_ to do a minor
collection.

Can you tell us what the problem is that you're trying to solve?

I've only seen two cases where I'd want to stop the GC from running:
(1) During quasi real-time operations (eg. a single frame in a game) --
this can be solved by making the heap large enough and running the GC
at scheduled points.  (2) When the heap is larger than physical RAM --
this is solved using our 'Ancient' module.
