Thanks for sharing, so basically you're doing #1, and using xscreensaver to
decide if mythfrontend is active or not instead of some dirty lsof/strace
It's obviously not my favourite because I have to kill mythfrontend which
could be paused in a middle of a show, and therefore when I resume, I lose
where I used to be, but it's better than nothing.
