^^^^^^^^^^^^^^^^^^^^^^^^^^
Linux can only be expected to stay up 248 days, at which time the
100Hz jiffy counter will go negative. Solutions are:
1. Slow down the clock
2. Run on an alpha (1024 Hz and 64-bit jiffies)
3. Initialize jiffies to 214748000048 and debug what happens after an hour
4. Add the line
/sbin/shutdown -r +705600 "running out of jiffies"
to your /etc/rc.d/rc.local (thanks, Werner)
