Make RPC tests cope with server-side timeout between requests

Browse source 
Python's httplib does not graciously handle disconnections from the http server, resulting in BadStatusLine errors.
See https://bugs.python.org/issue3566 "httplib persistent connections violate MUST in RFC2616 sec 8.1.4."

This was fixed in Python 3.5.

Work around it for now.
