 A number of operations restart X

  * Switching desktop from GNOME to Sugar
  * Other Sugar control panel options that require a Sugar restart

 If you try them quickly, it can trigger upstart's "prefdm respawning too
 quickly" control, which effectively kills X.

 Related to #4561. Definitely present in 11.3.1 and earlier builds.

 Our new OS in development (12.1.0) has a different init system. After
 initial testing, it does not seem to have this problem.
