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
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).
