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.
