* check task toggles the onboard LED. Should any task contain an error at any time

* The "Register Check" tasks. These tasks fill the CPU registers with known
* values, then check that each register still contains the expected value, the
* discovery of an unexpected value being indicative of an error in the RTOS
* context switch mechanism. The register check tasks operate at low priority
* so are switched in and out frequently.
