In fact there are _no_ double key press issues with the input system.

The 'problem' is that the keyboard driver and the the application
attached to /dev/input/eventX receive a key press from the remote
control.

Solution:
The application must grab the input device for exclusive access.
In other words: Get LIRC fixed. ;-)
