Things that run in the background, such as TV-XGP-HARDCOPY, lose becuase they
compete with other processes.  The right behavior should be that they only run
when no non-background process need the processor.  I suggest we distinguish
between background and non-background processes and run background processes
when the foreground activity has been quiescent for a period of time, maybe a
couple seconds (to keep the paging down).

Thus background processing would get done if the user had nothing to do while
it would stop as soon as he did have something to do giving him the full
processor.
