Well, I'm not really back, not online etc.,
but this looks very much like some internal
built-in plausibility check for proper frame
nesting - something that Stackless in fact does not
try to support. I guess we need a special build that
avoids certain plausi checks in certain situations.

One would need to dig into some source to solve this
problem. Something that I will not do often in the
future :-)

Any volunteers would be appreciated.
