 This is a followup to #24991, which has two of the config files (tor
 config, and tor log)

 Expanding on the description in #24991, my blog has a low traffic single
 onion - barely gets hit over Tor at all - yet when I investigated it
 recently I found it claiming to have 6 circuits open for an extended
 period (~days) and also ~50 simultaneous TCP connections.

 I confirmed this with netstat, and then by killing the Tor daemon which
 threw all the connections into simultaneous TIME_WAIT.

 I mentioned this to Teor on IRC, who suggested that I log " a ticket about
 expiring single onion and tor2web connections, please" - because this
 seems really strange, and suggests that SingleOnions are not garbage-
 collecting properly.
