-------------------------------+-------------------------------
 Every time that a relay is measured, it is first checked whether
 destination is usable, and then run connect_to_destination_over_circuit,
 which checks again if destination is "usable".
 It implies two locks, and a destination can fail in a row due to the relay
 being unstable.
 It'd be better to determine that a destination is not usable, either by
 trying to make a connection not over Tor, or after a X number of failures
 in a row.
