Paul you should be looking to see why other tasklets don't rendezvous with the
waiting tasklet's channel?

Paul, it has been a while since I played with threads and stackless. I found
threads and queues typically hid a design problem. Then again, I haven't used
UIs.
I believe to keep the application alive, I did something like:
<your code goes here>
while flag:
stackless.schedule()
in the main tasklet. If there is nothing, only the main tasklet gets scheduled.
I believe there is an example in the Stackless Google repository.
Again, I would have to look at the code. However when you need queues and dummy
tasklets, it sounds like there is a more straightforward solution.
Cheers,
Andrew
