When this program is run with Sleep() instead of boost::thread::sleep(), and there are no other cpu intensive programs running, Task Manager shows 99% of the cpu (dual core) is idle. However, when it is run with boost::thread::sleep(), 99% of the cpu is being used by the program! This is a problem because powersaving features no longer work.
When this program with boost::thread::sleep() is run with another program that is cpu intensive, Task Manager reports the other program uses 99% of the cpu, so there is no problem there.
I am using an overclocked Intel Core 2 Duo 6400 if that matters.
