The problem of course is if you import a module which itself uses stackless.

Currently, there are limited ways in which simply importing a module can
kill Python. This would add another way. Obviously all such modules should
be documented, but ...

I'm not saying I'm against Stackless - quite on the contrary. However, it is
something which needs to be considered *very* carefully.

At the very least, PyChecker should warn about Stackless (even if it never
gets into the core ;)
