Lol, when I read that I wondered how long it will it take before someone _did_
respond with "It's a flaw in the design"
I actually was trying to do this _exact_ thing (making pb appear synchronous)
and met with similar remarks to my post for help. But even though I did
manage to write a hack using a interleaved threadedselectreactor,
threading.Event and a forced event processing while loop, the result was
mostly functional but ugly and a pain to debug.
It was a flaw in my design.
And after some serious reworking and acceptance of a more asynchronous
methodology, my program is the better for it. Way better.
In short, I would recommend _not_ forcing/hacking twisted to be something its
not. Use L. Daniel's suggestion, use a synchronous network system like
xmlrpclib, or rethink the meta problem your are trying to solve.
