So, it seems like most of the time python scripts will work with HUGE_STACK_SIZE
turned off, but every once and a while some scripts will fail in non obvious ways
that could leave a person scratching their head for weeks trying to get to the bottom of it

To me, it seems like the best behavior would be to default to compiling with that set. I'll create
a patch over the weekend and open a PR
