This works, but then the question is how to proceed with the next
dWorldStep.  I have no good ideas about that.

If the stack exceeds physical RAM that's gonna be a problem no matter what
OS you're running.  Virtual memory would probably take over, so you'd just
slow down, but I bet you'd slow down an awful lot. :-)

I used to think this was the best solution, but if you're right about the
stack being allocated as need up to the option specified during the link,
then there's no reason NOT to set the stack size to HUGE_VAL.
