The patch might fix part of the problem, but there remain more issues:

* SDL also sends an SDL_KEYUP event for caps lock when the
   environment variable SDL_DISABLE_LOCK_KEYS is set.
   This mode is very useful but currently unsupported by qemu/kvm.

* Num lock and caps lock are handled in a similar way by SDL.
   The patch only handles caps lock. Maybe this is less important
   because keyboard layouts which remap num lock are rare
   (I don't know any).

* The keyboard status LEDs and the qemu client's keyboard status
   can become unsynchronized if the input focus changes from qemu
   to other applications.
