Comment (by TimeForGoToBed):

 Thanks, guys.  Glad you erred on the side of caution and made the new
 timeout a full 5 minutes.  As it turns out, I was premature in reporting
 that I was no longer experiencing the "Could not connect" issue.  While it
 was no longer the case, as in older versions of Tor Browser, that it would
 //never// succeed in connecting to the control port after the first post-
 install run, I've found that if my netbook is running other applications,
 the "Could not connect" returns.

 While experiencing the issue today, I tried various things that were
 unsuccessful in getting Tor Browser to successfully start up, including
 plugging into AC power to go to full-performance mode, switching from Wi-
 Fi to EtherNet, switching the priority of tor.exe and/or firefox.exe to
 High in the Task Manager just after startup, and even quitting all the
 other apps I was running.  Only rebooting got Tor to work again.  Intel,
 in their infinite wisdom, elected to limit my Atom CPU to being able to
 access 2 GB of RAM, so memory fragmentation and/or swapping may be
 responsible for the system being too slow to start up Tor within 30
 seconds unless a reboot is done.

 In any case, hope this does get backported to the next stable release;
 increasing the timeout seems like quite a safe change.
