This is open source, baby. So i'm glad there's some alternative to my messy code ;) And btw: the two programs are still a bit different. rt_watchdog is a daemon. I have wondered about how to make it known to the user that it has kicked in. The only solution i found was to write into the logs. Opening an xwindow is an interesting solution.

Might this not fail on SMP boxes? I think i make a similar mistake by using a volatile int (not as a counter, just as a exit state indicator) instead. Any gurus care to comment?
