I'd thought that each tasklet would run once, round robin style, with

back into the round robin queue.
Am I misunderstanding how stackless works? Because what I think I'm
seeing is that the receiving tasklet runs immediately. I don't have
any call to stackless.run, but as soon as I call send on a channel,
the receiving tasklet runs, rather than having the send queue up until
the tasklet is next up to run.
This behaviour is defined by the 'preference' attribute of the channel:
help(stackless.channel.preference)
Help on getset descriptor __builtin__.channel.preference:
preference
-1 prefer receiver (default), 1 prefer sender, 0 don't
prefer anything. See also schedule_all
You probably want to set it to 1 for your channel.
FWIW, my guess is that he wants the 0 preference, just adding
the receiver to the round robin list.
