[Stackless] Context Switch

Hi Austine Jane,

At the moment, it only does a context switch, when either
a channel is resuming a waiting takslet, or if you just
schedule() to the next runnable tasklet.

You will be able to do this, pretty soon.
I'm just fixing some issues with the new Stacless 3.0
main feature: pickling of tasklets.
When this is done, the stackless.run() method will
grow a timeslice parameter, which controls how often
to switch tasklets, automaticlly.
(No fear: This will only happen to tasklets which have
explictly been registered for explicit scheduling).
