Comment(by robgjansen):

 So I re-ran CircuitPriorityHalflife 30, not patched, with info level logs.
 Looks like the problem did not appear this time:
 {{{

 }}}

 I re-drew the
 [https://trac.torproject.org/projects/tor/attachment/ticket/6341/20120813-ec2
 -brokenewma-combined.pdf client performance graph] too, just for fun. The
 blue lines contain the new results.

 I'll send the logs, though I'm not sure they will be useful.
