Comment(by nickm):

 Replying to [comment:29 andrea]:
 > Making sure I understand this correctly: this is better than the max
 queue length version because the maximum is controlled by the amount of
 memory available globally, so the queue fill has to be much, much larger
 to force a circuit kill needed for the potential exploit?

 Right.  With all of the algorithms I outlined above, we only kill circuits
 once we're really about to be out of memory.  So the tricks described in
 the original ticket here (and in the first comment) aren't sufficient to
 force a circuit kill.
