This won't work correctly in some cases from what I see.  The  
CLIPBOARD and PRIMARY selections are just owned.  And once owned it  
seems not all X11 apps will set ownership again (e.g. Tk and possibly  
others).  They don't technically have to.  So we have the same  
ambiguous situation as before.
