Hmm... isn't this the same on all other GUI systems?
kbd_buffer_store_event adds the event to the Emacs input queue, and
AFAIU it will be processed as soon as Emacs gets back to its main loop
and calls read_char.  No other event should be needed, AFAIK.  Po Lu,
am I missing something here?

I know nothing about the "NS event loop", so I'm probably missing
something.

Thanks.
