That should read "however *it* wants".

sorry, my question wasn't clear:
I do already disable Nagle by setting TCP NoDelay.
And I do a reactor.select(0), which sometimes breaks I guess
because of reactor reentry not expected, and it will break
when the reactor is not select() based I guess.
So the question is: is there an alternative

You can disable nagle in Twisted, if that's the question
(transport.setTcpNoDelay(True)). But you can't determine TCP packet size,
that's up to the operatin
yes. for FF and Chrome, and other WebSockets clients

alternative to disable nagle (tcp nodelay) and doing a select()?
ps: to give an example of how that was at least practically useful in what i
try to do .. and not only blabbing away:
http://www.tavendo.de/autobahn/testsuit
well, it does not necessarily correspond, but from what I see on tcpdump with
loopback device and on LAN (with TCP NoDelay set), it practically works.
the problem with your suggestion: I want to test the other end .. and that is
not Twisted (its i.e. Firefox .. the protocol to test is WebSockets)
