Test whether Tor hidden service patch is still needed
Repeat the Tor performance experiments from #115 (closed) using Tor 0.2.6.7 with the old and new code to determine the impact of improvements to Tor itself, specifically issue #8239 (https://trac.torproject.org/projects/tor/ticket/8239).
Repeat the Tor performance experiments from #115 (closed) using Tor 0.2.9.15, with and without our hidden service patch, to see whether our patch still affects performance. Test the patch from issue #19522 (https://trac.torproject.org/projects/tor/ticket/19522) to see whether it would be a suitable alternative to our patch.
If our patch is still needed, update it to address the reviewers' comments from https://trac.torproject.org/projects/tor/ticket/18620. That ticket should be closed, as v2 hidden services are being deprecated. If we need a new patch for v3 hidden services we should open a new ticket.
