[Twisted-Python] concurrency via reactor

[Vadim Zaliva]

Hi!

I am writing some code which requires synchronization between several
TCP clients. I have several connections and at some point I have to
wait for data becoming availiable from several of them. Kind of
"barrier" pattern. I am twising my head how to do it with twisted
using reactor. Could somebody point me into right direction? Thanks!
