This is not directly binding Stackless to PyPy, but a bit.
The idea is to produce a Stackless module by writing it
in RPython as much as possible. Then it would be translated
into C and be used by Stackless.

Well, I'm not completely decided on this. The PyPy version of
stackless is quite nice because it factors the building blocks
into smaller ones. Everything is based upon a coroutine
implementation. Greenlets and Tasklets are derived classes,
and it is pretty simple to create even more variants.

Of course there are some missing parts which can't be handled
right now. PyPy only does soft-switching. Hard-switching
will probably be developed when it is needed, and right
now we are not calling out into external libraries.

I don't expect that to happen in the next half year, I'm
just expressing how I would like to move towards a more
flexible and configurable implementation.
