I have each task set a flag in the watchdog task each time it runs.
For tasks that run on demand, the watchdog task will send them a message periodically, and give them time to run.
For each task the watchdog makes sure that the flag has been set, then it clears it.
If any of the flags did not get set, the task is declared dead and the hardware watchdog does not get strobed, the system reboots.
