[Twisted-web] Having reactor run at the main thread make things harder for late adopters

[Tzury Bar Yochay]

I will first describe my application in a single sentence.

Write a server that can serve TCP/UDP clients on several ports, and
let the clients communicate with each other in a predefined protocol,
while each can 'talk' to the server in a different protocol/port.

In my case where I picked up Twisted relatively late in the project I
need Twisted to plugged into my applocation and not the my application
plugged-into Twisted (at least at this stage).

Is there a way to by-pass this limitation?

At this stage the main problem I see is having transport.write will
have data transmitted immediately when called from another thread.
