Comment (by nickm):

 Without this patch, the startup looks like:
 {{{
 Oct 08 12:14:06.000 [notice] We now have enough directory information to
 build circuits.
 Oct 08 12:14:06.000 [notice] Bootstrapped 80%: Connecting to the Tor
 network.
 Oct 08 12:14:07.000 [notice] Bootstrapped 85%: Finishing handshake with
 first hop.
 Oct 08 12:14:08.000 [notice] Bootstrapped 90%: Establishing a Tor circuit.
 Oct 08 12:14:09.000 [notice] Tor has successfully opened a circuit. Looks
 like client functionality is working.
 Oct 08 12:14:09.000 [notice] Bootstrapped 100%: Done.
 }}}
 and no other bootstrapping events are reported.

 With the patch, startup looks like:

 but not enough to build a circuit: We need more microdescriptors: we have

 This looks right-ish to me, though this could be a bit verbose.  Do we
 want this for 0.2.4 or for 0.2.5?
