I would like to call XtGetSelectionValue while in a command 
widget callback.

In order to be ICCCM compliant (to avoid race conditions,
I suppose), the time stamp of the mouse down event that 
triggered the callback needs to pe passed as a parameter.  
The toolkit however seems to hide the XEvent record.

One solution is to register an event handler with the command 
widget, using XtAddRawEventHandler.  When that handler is called,
cache the XEvent in a global, and then assume that the callback is
called immeadiately after the event handler (so I can depend
on my cached XEvent being correct).  

Is there a cleaner way to get the time stamp?
