Adjusting the parents watchdog timer

[Dave Cheney]

Adjusting the timeout to 15 seconds has keep a machine which was  
previously restarting the child up to 4 times a day stable for over 24  
hours.

Clearly the watchdog timeout exists for a reason and adjusting it this  
high is only a placebo. I'll try reducing the timeout slowly  to  
figure out exactly what is causing the child to timeout.

Cheers

Dave
