Why you are getting an exception printed is unclear from the code you
have provided. You would need to provide a reproduction case so the
problem could be observed. Or at the least, the exception trace given
it is some Stackless caused problem and not a side-effect of your

You can empty the scheduler by enumerating the tasklets in the
scheduler. This can be done by getting the current tasklet (t =
stackless.current) and stepping through the chain of scheduled
tasklets (t.next, t.next.next, t.next.next.next...).
The following code is untested and may not work:
ct = stackless.current
while ct.next is not ct:
