I can't see any explicit methods for this in the API. The problem is
that it is calling WSDLActivity.configure which tries to parse the WSDL.
It is the multiple (sequential from the look of the code) timeouts on
the fetching of the WSDL that is causing the overall delay.
I think the easiest way would be to put the parser.createDataflow in a
thread and then have a timer that after 5 minutes kills off the
createDataflow thread if it is still running.
