 I am used to rise the priority of debug/interactive console at FIFO
99 on those system I know there are a problem with user interaction. I
am conscious that a solution like this could harm the system if debug
console is used by not acknowledged people in a not properly way. So,
it is a solution only when falling down on debug console is the last
chance to interact with the busy system.
