Subject: [PATCH] Bug 554924 - Weave should not sync during session restore
 [r=mconnor] Get rid of STATUS_DELAYED and initialize Weave listeners, etc
 immediately. At the end of onStartup, wait a little bit to let sessionstore
 restore tabs and then count how many busy tabs to delay autoconnecting to
 avoid doing network while tabs are doing network.
