Comment:
I can take this one. But I want to get this clear. If I summarize what we
have here and what we need to decide:
* Fortunately, we do track OR connection failure in `rephist`, see
`rep_hist_note_connect_failed()` so we could use the `or_history_t` to
know if we should try to connect.
* We'll need to decide on a "how long before I retry to reconnect" timing.
We could do a simple "backoff algorithm" like 1 sec, 5 sec, 10 sec and
give up.
* Once I've identified that tor can't reach a specific relay, how long
should we consider it "unreachable"? Or should we repeat the above if no
retries are pending?
* Should we keep the EXTEND cells while waiting for a reasonable amount of
time before reconnecting? That is, if we have a failure to connect, should
we just DESTROY the circuit or retry to connect and send the cell(s)
later?
* Should we consider the disconnects and "I've just waited 60 sec before I
got anything back from you" as potential failures also to note down?
