[mythtv] how to clear the key buffer (mythgame)

[Geoffrey Hausheer]

I've got a PC game setup with mythgame, which takes a long time to
load.  Sometimes my wife/me/whoever gets impatient and hits the select
button more than once, thinking  the last press didn't register. 
however, once the game is over, thoose other button presses are still
queued, and the game will relaunch again immediately.  So I'm
wondering how to flush the key-buffer once the game exits
This seems like it should be availiable through Qt's event-handler,
but  I couldn't find an easy answer there.

Any hints?
