 Replying to [comment:2 catalyst]:
 > That's one possibility, but the Tor Launcher devs have rejected that
 before for various reasons, and this is the best way to get a substantial
 usability improvement with the existing Tor Launcher.

 Hmm. I don't think we rejected that idea. When Kathy and I experimented
 with it, we found that in our testing it did not solve the problem.
 Specifically, a CLOCK_SKEW event was generated before Tor Launcher had
 established its control port connection, so Tor Launcher did not see it.
 But as I write this I wonder if our testing was flawed, because if we
 start tor with DisableNetwork=1, then connect to the control port, then
 monitor STATUS_GENERAL events, it seems like we would see the first
 CLOCK_SKEW event (but I know very little about tor internals).

 Anyway, somewhere I have experimental code that monitors CLOCK_SKEW
 events... so if that is the Right Thing To Do we can add it to Tor
