* Some functions require the request queue from the server to be flushed
* so that the ordering of client initiated status changes and those requested
* by the server is well defined.
* _XimSync() would be the function of choice here as it should get a
* XIM_SYNC_REPLY back from the server.
* This however isn't implemented in the piece of junk that is used by most
* input servers as the server side protocol if to XIM.
* Since this code is not shipped as a library together with the client side
* XIM code but is duplicated by every input server around the world there
* is no easy fix to this but this ugly hack below.
* Obtaining an IC value from the server sends a request and empties out the
* event/server request queue until the answer to this request is found.
* Thus it is guaranteed that any pending server side request gets processed.
* This is what the hack below is doing.
