Expand point 3.13 of the FAQ

[mathias]

I suggest to add a third point to point 3.13 of FAQ: http://twistedmatrix.com/trac/wiki/FrequentlyAskedQuestions#WhydoesittakealongtimefordataIsendwithtransport.writetoarriveattheothersideoftheconnection:

If your program appears to send messages as expected, it might also happen that the sending program is working as expected and that the receiving program buffers the messages! Eg: your messages are buffered by a web browser, and you don't close your message! Use telnet instead. Especially as a beginner, never forget that you can only see messages indirectly through the eyes of another program. Check your receiving program!

It's just about adding a few lines of documentation.
