I'm not sure what you are saying, but yes there are 1 million microseconds in a
second.... 1000000 micro seconds that is. So my loop seems correct. Also, I am
running this on a 2 GhZ processor, so I doubt the 1000 calls to usleep can add that
much overhead. I think something is wrong with the library or the kernel.
