I was suggesting that more for testing to find the problem than a clean
solution.  It might be illuminating to disable interrupts immediately before
the sleep and see how the bits come back after wakeup before any other code
runs.  Is there a CLRWDT in the ISR?  If so, could some other interrupt be
true on wakeup so that TO gets reset before you can see it in the main code?
...  Just grasping at straws.
