Comment (by phw):

 I added a log message to BridgeDB that tells us how many bridge requests
 resulted in 0, 1, 2, and 3 bridge lines.  Here are the results for a few
 hours worth of logs:
 {{{
    # of bridges | # of requests
    -------------+--------------
               0 | 188 (14%)
               1 | 381 (29%)
               2 | 395 (38%)
               3 | 235 (18%)
 }}}
 (Interestingly, all requests that resulted in 0 bridges were HTTPS
 requests for obfs2, coming from Tor exit relays.  BridgeDB no longer
 supports obfs2, which is why it responds with 0 bridges.)

 Assuming that these numbers are correct, BridgeDB should be returning at
 least one bridge for every request it has seen over the last few hours.
 That clearly wasn't the case a few days ago but I wonder if it's the case
 now. The only thing that changed is that I added debug log messages and
 restarted BridgeDB a few times.
