Sub-millisecond precision timing in C or C++ http://stackoverflow.com/questions/2904887/sub-millisecond-precision-timing-in-c-or-c OS and configuration On windows you can change the default scheduling period of 100 s to 1000 s using the multimedia API . This can.. get right but essentially you need determine when the OS scheduling periods occur and calculate the one prior to your target wake.. if not until your target time arrives. Occasionally OS scheduling will cause you to miss but generally speaking this mechanism..

What are the common causes for high CPU usage? http://stackoverflow.com/questions/9275262/what-are-the-common-causes-for-high-cpu-usage OS who makes decisions like context switch interrupt and scheduling as to which thread should be given access to system resources.. it will just always be available whenever something needs scheduling and hence will tend to get scheduled. For your example loop..
