---------------------+---------------------------
 Perhaps: we should replace the tahoe start command something very similar
 that tails the long looking for a magic string and then exits. If magic
 completion string is not found then report an error to the user telling
 them to look at the log file for more info.

 We would like to systematically iterate towards an asynchronous startup
 for tahoe... because we've got an accounting database that needs async
 startup... and the accounting db is needed for everything else. There are
 many failure paths that can occur on startup and we'd like to catch all of
 them as soon as possible and report them to the user instead of what tahoe
 start does: background the daemon and report nothing to the CLI. Silently
 fail.
