Comment:

 Yes, you will still eventually run out of memory and get a heap overflow
 error. See [[GhcFile(rts/Schedule.c)]] for how we deal with this case; we
 actually service stack overflow errors during the normal operation of
 programs, because we use stack chunks and we need to allocate a new stack
 chunk when we run out. So actually, it's pretty simple to make sure we
 give the right error when we run out of heap, change this line in
 [[GhcFile(rts/Threads.c)]]:

 {{{
 new_stack = (StgStack*) allocate(cap, chunk_size);
 }}}

 (as well as allocate) so that if requested heap allocation fails, it
 reports a stack overflow, not heap overflow. This should be pretty easy to
 do, patches welcome!
