    grdc(6): Fix 100% CPU usage and make timeout work again
    
    grdc(6) was passing a timespec with tv_nsec = 1000000*1000, which is
    invalid.  So every nanosleep() call just returns with EINVAL error.
    This causes grdc(6) to loop hard and uses 100% CPU.  It also brreaks
    the optional timeout argument; grdc(6) just exits immediately.
    
    Fix the above issue by correctly setting the timespec argument.
    
    This fix also makes the optional timeout argument work again.
