I'm not sure it's really feasible to do that. It seems easy
enough at first sight, but keep in mind that it would only work
for pure Python code called directly from other pure Python
code. There are many corners where it wouldn't work -- all the
operator methods, for example, and anything else called through
a type slot -- unless you went to a *lot* of work to provide
alternative suspendable versions of all the type slots.
