In [ruby-core:36931], ko1 told us GC eats stack when marking nested
objects.  Kurt's patch should allow us to run smaller pthread stack
sizes while still supporting deeply-nested structures.

Kurt: can you test a smaller stack size with your patch with some
deeply-nested objects?

Thanks, I'm excited about this patch :D  (but unlikely to have time to test
until next week).
