After some research, I think it actually has to do with the value of the
'backlog' parameter when creating a Listener instance: if there are too
many queued requests to a socket then further connection requests are
refused; the 'backlog' parameter appears to set the maximum size of the
queue.
...or something like that. I'm a novice here... :-)
Anyway, in the __init__ method of the Server class, in managers.py, the
Server creates a Listener instance with the line
self.listener = Listener(address=address, backlog=5)
When I change backlog to 50 instead of 5, I don't see the connection
refused error any more.
I'm not suggesting that the backlog value should be changed---it
probably shouldn't. But this does at least explain why connections can
be refused, and why they should be retried in that case.
I do still think that the patch, or something like it, should be
applied.
