Description
When running two CPU-bound single-threaded tasks (e.g. malloc1 test) on a 2-way SMP machine, the load balancing thread moves both of the mostly-ready threads (as well as most of the other ready threads) to a single CPU, keeping the other CPU almost idle. This renders in a very suboptimal utilization of the CPUs.
