    As a
    consequence, the toolkit does not know if anything has happened at all,
    so it doesn't know whether to wait for the ConfigureNotify or not; and
    it has no idea of which ancestor it should look for it on.

The toolkit doesn't need to know.  The expectation is that you wait at
the point where you attempt the top-level geometry change, not that you
delay waiting until you attempt something that depends on the move.  The
thing/point at which a top-level change is requested should be able to
deal with this (e.g. the Shell widget in Xt).

The assumption is that this is a rather rare occurance (for windows
that are managed by the window manager), so that the delay is tolerable.
If you have data to the contrary, or have a specific proposal that is
simple and more efficient, please present the information.

[We should do this either just on xpert, or just privately, so I don't
have to redo what I've said privately.]
