    Do not emit debug printfs under NODEBUG
    
    These printfs spew to the console when command-line utilities
    such as 'klist' and 'aklog' are run, reducing usability.
    
    These printfs can also cause application hangs.
    On a multiprocessor machine, when PuTTY and the ccapiserver are
    running on different CPUs, PuTTY appears to deadlock with three
    concurrent threads inside cci_debug_printf().
