I had a similar problem when i was using asynchat.fifo, it had a list in the past now it has a deque. So in order to put something to zeroth location (to be compatible with python 2.3 and python 2.4) I did something like: class fifo(asynchat.fifo):     def __init__(self, list=None):    asynch

Normally when you make a nonblocking connect, socket gets EINPROGRESS, later the result of this request will appear after select returns.   I think asyncore/asynchat incorrectly interprets asychronous connects.
