 Replying to [comment:2 mikeperry]:
 > I am tempted to simply remove the has_opened -> cannibalized timeout
 differentiation, and simply use the desired_path_len for cutoff selection.

 Wow, after running this fix for just a few minutes, and I'm now seeing
 desired_path_len's of 5 for purpose 6. Is that a different bug, or do we
 also need a fivehop_cutoff for hidden services circuits for some reason?

 I'm going to let this run for a few hours and see what the final counts
 look like.

 Meanwhile, if anyone knows why hidden service client circuits with a
 purpose of CIRCUIT_PURPOSE_C_INTRODUCING would have a desired_path_len of
 5 in normal operation, that would be useful info.
