1-hop circuits are opened by tor to download descriptors and network
status documents.
3-hop circuits are opened by most tor clients to connect to exits and
onion services.

But sbws sets `__DisablePredictedCircuits 1` after bootstrapping, so sbws'
tor only has its 3-hop circuits from when it bootstraps. When they expire,
there are no more 3-hop circuits, so tor stops opening circuits.
