  Bug#35997 Event scheduler seems to let the server crash, if it is embedded.
  
  The event scheduler was not designed to work in embedded mode. This
  patch disables the system variable 'event_scheduler' used to activate
  the event scheduler when the server is compiled in embedded mode.

  mysql-test/r/events_embedded.result@stripped, 2008-05-07 12:15:28+02:00, thek@adventure.(none) +2 -0
    Add test case to make sure the 'event_scheduler' can't be activated
    in embedded mode.
