Would you like me to vary it based on 32-bit vs 64-bit?
I think so, but I'd like to hear from others about this.  Paul,
Andreas, could you please comment?

A 64-bit Emacs should need more stack space than a 32-bit Emacs, yes. It wouldn't be double the space, since not everything on the stack is a pointer or an EMACS_INT. If you really want to fine-tune it you can also depend on the width of EMACS_INT. Getting it "just right" would be a bit tricky.

8 MiB/thread for 64-bit Emacs sounds OK to me. I wouldn't cheap out on 64-bit platforms.
