* requests coming from inside the window hierarchy. If we
* accidentally interpret a response to our request as a user-
* initiated action, the window will stop responding to new geometry
* requests. To make this distinction, (a) this function sets a flag
* for TopLevelEventProc to indicate that we're waiting to sync with
* the wm, and (b) all changes to the size of a top-level window are
* followed by calls to this function.
* 2. Races and confusion can come about if there are multiple operations
* outstanding at a time (e.g. two different resizes of the top-level
* window: it's hard to tell which of the ConfigureNotify events
* coming back is for which request).
* While waiting, some events covered by StructureNotifyMask are
