How is this possible? The load average is just an indication of the average number of processes waiting to use the machine at any one time. It can get very high, over 100 under some circumstances. The reason you can run your other applications is because of load balancing. fvcool is running at a low priority (higher number). I still suspect it's not supposed to consume all that CPU time, though, and I find it rather strange that this should help cool the CPU.
