With this turned on, the task WDT can detect if the idle task is not called within the task
watchdog timeout period. The idle task not being called usually is a symptom of another
task hoarding the CPU. It is also a bad thing because FreeRTOS household tasks depend on the
idle task getting some runtime every now and then.
