New submission from Serhiy Storchaka:
sched.scheduler.run() blocks scheduler and prevents the addition of new events
until all events added before start will not be processed. Canceling does not
work too.
Here is test script which reproduces the behavior differences.
Output in Python 3.2:
Adding
adding 0
added 0
adding 1
added 1
adding 2
added 2
event 0
event 1
start event
event 2
Canceling
Output in Python 3.3:
Adding
adding 0
start event
added 0
adding 1
added 1
adding 2
added 2
Canceling
event 0
event 1
event 2
