Code review comment for lp:~compiz-team/compiz/compiz.performance_1027211.2

Also, without too much verbosity, why is it we need to implement window movement completely synchronously? My understanding is that waiting and locking should never be required when the user moves a window.

A window move should simply involve two events:
  1. Motion event -> move plugin -> send request to X server (XConfigureWindow I think).
and some time later (should not care when):
  2. XConfigureNotify (or whatever) -> core plugin -> compiz window position updated.

If this is lazy positioning then maybe I do support it. But historically we seem to have a lot more code than should be necessary to implement movement so I'm not sure.
