Something like ClientCreator (a convenient way to connect and get a protocol
instance when it is connected) with blockingCallFromThread (in SVN Twisted, so
the calling thread can get access to the result of the deferred from
ClientCreator) would probably do the trick.
If these aren't directly usable, you may find inspiration from looking at their
