Starting an INDIVIDUAL instance of a subclass from asynchat

Question

So the situation I have is that I have loaded more than one class that I've made that subclasses from asynchat, but I only want one of them to run. Of course, this doesn't work out when I call asyncore.loop() as they all begin. Is there any way to make only one of them begin running?

edit: I think it has something to do with the map parameter that can be passed to asyncore.loop but I can't get it working.

edit2: I got it. Basically I did the following:

asyncore.loop(map=my_instance._map)

Answer 1

For all who were curious, I figured it out. If you pass your instance's _map to loop() it seems to only start the single instance.

Example:

my_asyncore_obj = SomeAsyncoreObj()
asyncore.loop(map=my_asyncore_obj._map)
