So much has changed since I originally got the RPC tests working many years ago,
most notably modern Linux distros don't even have a way to install python2 via
packages, you have to install from source. Continuing with python2 does not seem
like a good idea, so we begin migrating thigns to Python 3.
Currently running ./test.sh will successfully spin up a test chain but then
the test suite crashes when attempting to send an RPC request, which looks
to be caused by the test suite internals still expecting python2.
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.
