Actually, now I am a little doubtful that this patch is complete.  If I 
recall correctly, we are merely enqueueing input events into a queue 
that the mi layer processes later.  Checking the mode key states within 
the X server will only indicate what the mi layer currently knows about 
the mode key states.  The my layer would not know that there are 
messages in its queue that change the state of the mode keys.

I also recall that there is a way to force the mi layer to process all 
input events (miProcessInputEvents ?) and that this could be called 
before querying the state of the mode key states in order to get a 
consistent result.

Please respond to this either with a rebuttal or a different patch.  I 
don't think I can commit the existing patch until then.
