[issue1641] asyncore delayed calls feature

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

I agree with the points raised against Josiah's patch. I'm not sure O(n) cancellation is really a concern. The main focus of optimization should be the scheduler's loop itself, and both approaches have an O(log n) complexity there AFAICT. Also, the cancellation optimization could be backported into Giampaolo's patch.

One area tests should check for is when scheduling operations are done from a delayed call. Especially, a delayed call rescheduling itself.

By the way, it's too late for 2.7, so this is only for 3.2 now.
