- *  1. This is the same as the regular CPU independent algorithm.

- *  3. Be warned. Some processors with onboard DMA have been known
- *     to stop the DMA if the CPU were put in IDLE mode.  This might
- *     also be a problem with other on-chip peripherals.  So use this
- *     hook with caution.
+ *  Stop until we get a signal which is the logically the same thing 
+ *  entering low-power or sleep mode on a real processor and waiting for
+ *  an interrupt.  This significantly reduces the consumption of host
+ *  CPU cycles which is again similar to low power mode.
