Comment (by isis):
To update, now I'm not sure how well this is working. It's definitely not
doing ''worse'', and it ''might'' be doing better. But I am once again
getting warning messages on my test relay that tor's fd usage is at 90% of
its maximum. The NTOR queue is pretty consistently empty, and the TAP
queue seems to fluctuate around the 300-400 range. One problem which seems
to have surfaced is that the EXTENDCIRCUIT cells have expired by the time
they reach the front of the TAP queue, so Nick's idea to create some sort
of probabilistic prioritization of NTOR requests is probably a good idea.
