/*
     * This is not meant to be driven by the normal unit test process.
     * 
     * To run, fire up two shells and run the first one with this test and with no parameters. Take the Uid
     * that is printed out and use it in the second shell with the same test and the -uid option.
     * 
     * Optionally provide a value through the -val parameter on one or both of the shells.
     * 
     * If you are fast enough then you should see something like ...
