Ok great, but, that means the "nat prober can't keep up" issue isn't a
scalability bottleneck, it is a bug in the nat prober -- where sometimes
it decides to stop probing, for reasons we don't understand?

If so, then better load balancing
(https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/75)
won't necessarily solve the issue.
