Well one get's still a mux process and also the messages (when debugging
is on) on the "master sesssion" that others try to re-use it... but then
they're blocked.

Well I don't really think I have any issues... I just wondered whether
there are any other side-effects than having influence on the channel
muxing ... perhaps something like "only accept 1 session from the same
IP, even when not muxing".

What is the issue you guys found?
