Hm, this would be problematic.  Am I right to assume that multiple
threads suffer the same performance hit on this architecture?

If you can't inline a generator, though (e.g. if the generator object
is stored somewhere), you'd have to revert to stack-switching, so it
would still be needed in some form (as you later imply).
