Comment (by simonpj):

 FWIW I believe that in other systems (e.g. ML) they started using guard
 pages, and moved away from it becuase it was SO HARD to make it work: on
 different archiectures and OSs, accommodating the non-standard calling
 conventions we use; dealing with correct GC of the registers that are
 saved on the trap; dealing with the fact that the stack we have is tiny,
 unlike the OS stack.

 If I had 1,000 hours to invest, I would invest it elsewhere. I'm not
 saying you couldn't make progress here, just that I think you'll find a
 better cost/benefit ratio elsewhere.
