X11 has no way to reliably transfer grabs between clients. I don't 
think that Xsync will make any difference here, the flush ensures that 
the wm process has ungrabbed by the time the menu process attempts to 
grab. Making the wm wait for the ungrab to finish before sending the 
commands to the menu process would only make the latency before the 
menu appears longer

the timestamp from the current event is passed through to 
gtk_menu_popup (), it's used when trying to grab the keyboard and 
pointer to avoid cancelling a later event
