Really? I do check events by 'showkey', the output of showkey is not the
events sent from keyboard?
# showkey -s (show keys' scancode)
I can always see many down scancodes, and one up scancode.
It's same when I disable / enable auto-repeat mode in system.
In the real host / vnc guest/ sdl guest, hold one key, many down
events can be checked by showkey.

"""
If you hold down a key long enough to start the keyboard's repeat
feature, the system sends multiple key-down messages, followed by a
single key-up message. """
key-down messages == key-down events?
