[RC5] Adverse effects of NON participation!

Has anyone bothered to look at the additional stress on the CPU that is not
running the client? As an example, consider a server that usually sits idle
but periodically gets a burst of work. The CPU on this server is going to
be cool while idle between jobs then quickly heats up when a job starts and
cools down again when the job is done. Differential temperature changes
during these heating and cooling cycles are going to create thermal
stresses on the chip. These stresses can cause minor flaws in the chip to
expand until a critical circuit is broken and the CPU fails.

By running the client the CPU is always busy so the thermal variations will
be minimized.
