New description:

 skruffy is reporting hangs on Torbutton's New Identity. Oddly, the hangs
 seem to be more common if you are loading a bunch of websites at the time
 of hitting New Identity, but that is not a full repro case.

 The hang actually appears to be happening while attempting to open a
 control port connection. Perhaps another race introduced by our SOCKS
 optimistic data hack in nsITransport? Or perhaps our hack for #8642 is
 insufficient in some cases, and/or during heavy network activity.
