 In old builds, we had "respawn" in the inittab line that runs olpc-dm.

 However, respawning the X session whenever it dies is a receipt for very
 annoying behavior in case of errors in the session.

 Using "once", the current behavior, is also inadequate: developers are
 used to zap the server with Ctrl-Alt-BS in order to restart their Sugar
 sesion.

 Users also get told to do it as a quick way to recover from memory leaks
 in the session without going through a full reboot. Some control panel
 features will also require restarting the session by killing the sugar
 process.

 A possible solution is: check how long the session lasted in olpc-dm.  If
 it's less than 10 seconds, exit.  Otherwise, respawn.
