One caution on multiprocessor systems:

from http://msdn.microsoft.com/en-us/library/ms644904(VS.85).aspx

On a multiprocessor computer, it should not matter which processor is called. However, you can get different results on different processors due to bugs in the basic input/output system (BIOS) or the hardware abstraction layer (HAL). To specify processor affinity for a thread, use the SetThreadAffinityMask function.
