We attempt to detect both network connectivity loss and drastic
changes in the timeout characteristics.
- We assume that we've had network connectivity loss if 3 circuits
- timeout and we've received no cells or TLS handshakes since those
- circuits began. We then temporarily set the timeout to 60 seconds
- and stop counting timeouts.

- If 3 more circuits timeout and the network still has not been

To detect changing network conditions, we keep a history of
the timeout or non-timeout status of the past 20 circuits that
