[Twisted-Python] Launching Twisted client using Process call

[naman jain]

Just to add to the previous post:

>>foo = Process(target=build_worker.main, args=(build_q,uid,))

is the statement I want to replace (because it is unreliable), with
something other that reactor.spawnprocess as there is no reactor in the
calling script.

Thanks
Naman
