Yes, and it is not what I intended:

    struct tv foo = { 0, 0 };
    select(0, NULL, NULL, NULL, &tv);

This is a way to give up your quantum; you might end up being rescheduled
or not.  In my mind "blocking" usually describes "waiting for a resource
to become available"; in this case you might not actually "block" since
you are not waiting for a resource.
