Hey Jean-Paul (and all the others in this thread), Thank you very much for your help so far - I do really appreciate it!
I'm well aware of the fact that `deferLater` does not magically turn blocking apps to non-blocking ones. The idea is, whatever SUDS does, in the end it should send a SOAP request to my TestServer. My problem is, that SUDS indeed sends the request, but wants to get an immediate response, which causes a deadlock. I just came across the very same question asked a couple of years ago: http://stackoverflow.com/questions/2671228/python-how-can-i-use-twisted-as- the-transport-for-suds This should help me out of this.
