I used to do something like the following:

I did not want setiathome to cause my server (which sits in a badly 
ventilated closet) to overheat. So I had written a C program that 
monitored the rate of the CPU fan (which is regulated by the CPU itself) 
and throttled the setiathome process (by sending it SIGSTOP/SIGCONT 
signals).

The result was that the setiathome process kept the server at a constant 
temperature (and the CPU fan at around 3000 rpm).

This ceased to work when the setiathome project changed their 
architecture, causing the work to be done by a load of sub-processes 
rather than the one I knew the pid of. So I dropped setiathome altogether.

I haven't kept stats, but the clock now looks less stable (frantic 
attempt at remaining on-topic).

Cheers, Jan
