#9776: Long-running tor client doesn't build new circuits anymore

------------------------+------------------------------------
 I'm running three tor 0.2.4.17-rc clients on ferrinii for Torperf, and one
 of them stopped building new circuits a while ago:

 {{{
 Sep 19 08:28:42.000 [notice] We'd like to launch a circuit to handle a
 connection, but we already have 33 general-purpose client circuits
 pending. Waiting until some finish. [1 similar message(s) suppressed in
 last 600 seconds]
 }}}

 The process is still running and I can debug it (though I should kill and
 restart it at some point to make Torperf work again).  I sent it -USR1 and
 -USR2 signals to dump stats and switch to debug log level.  I'm attaching
 the logs since last restarting it.

 Here's the torrc:

 {{{
 DataDirectory .
 SocksPort 9021
 UseEntryGuards 0
 RunAsDaemon 1
 Log notice file log
 ControlPort 10021
 CookieAuthentication 1
 PidFile tor.pid
 }}}

 Roger suspects it has to do with 0.2.4.x using guards as directory guards
 and this tor not using guards.
