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 lib=
rary or the kernel.
