Okay, I understand what you're concerned about now. Yes,
that's a nuisance, and it would be very nice to be able to
avoid it.

Unfortunately, I don't know how to implement your suggestion
in a fully general way without either resorting to dubious
C-level hackery as greenlets do, or turning the entire
architecture of CPython inside out as the original version
of Stackless did.

What I'm trying to do is see how close I can get to the
ideal, without hackery, by building on already-established
mechanisms in CPython and making as few changes as possible.
