------------------------------+----------------------------------
 Tor will try to reconnect to an introduction point up to 3 times.
 But rend_consider_services_intro_points() is called every second, which
 means that it uses up these retries very quickly, particularly if the
 connection fails quickly, like direct connections sometimes do on single
 onion services.

 It might be more sensible to retry slightly more slowly.

 On the other hand, maybe it's good that we fail fast and replace the
 introduction point.

 This behaviour was introduced in commit 1125a4876b4.
