[Twisted-Python] Socket Read Write

[Ted Patrick]

I am writing a chat socket server and need to make sure that there are no
conflicts when writing to other attached clients. I am concerned that when
the server receives lots of messages from many socket connections, several
sockets may encounter write contention. 

Is there a queue for the write method of a socket? 
Should one expect errors in this regard?
Does the Twisted architecture eliminate this class of error?
Using twisted.protocol.basic can 2 lineReceived events happen
simultaneously? How is this addressed?

Thanks,
