That is insufficient. The gtk main loop has more input
sources than just the connection to X:
- timers can be registered, which are called when the
   time comes
- idle handlers can be registered which are called when
   there are no other events
- child handlers are invoked when a child process
   terminates
- additional file descriptors can be registered
   (probably used for sockets primarily)
- a generalzed 'event source' can be hooked into it,
   with C functions for prepare, check, dispatch, and
   finalize
