Ugly script to sleep "accordingly" to CPU temperature, on loops

Sometimes you have a script or one-liner loop thing that may put quite a heavy load on the CPU, that can be at least bothersome due to the noise of the fan, or somewhat worrisome if the temperature approaches or goes beyond what the processor specifications recommend, and yet the system doesn't do anything by itself to avoid it.

One could simply add some arbitrary, constant sleep time within the loop, but that will likely make the whole thing slower than it needs to be. If within...
