1) Lets say you're writing a communications program that talks to some
    useful device over a serial port.  The device isn't as fast as the
    AS/400 and doesn't support flow control.
        a) if data is sent to the device at full speed, it loses 
            characters here and there.
        b) if data is sent with a 1 second delay, it takes forever.

2) Situation #1 is something I've run across several times.  However, I
    can imagine dozens of very similar scenarios to #1 involving other
    non-serial communications equipment, as well.

3) Any sort of animation... lets say you want to draw a man and have him
    walk around the screen.   (even if its just a text "drawing") at full
    AS/400 speeds, you won't even see the guy move.   At 1-second delay,
    it'll be REALLY slow and clunky.

4) Similar to #4 would be any type of computer game, audio application,
    video application.   Even if the 400 is only the server and there's
    a PC front end, situations are feasable where these delays would be
    practical.

5) How about a web server that deliberately slows down its response, to
     prevent a single user from being able to consume the company's 
     entire bandwidth?   Surely you couldn't do this effecively with
     a full 1 second delay!

Sure, you don't need it to write accounting software.  Do you really want
the AS/400 to be limited to only be able to run accounting software?!

The posters question was completely valid!
