I think we discussed this some time ago and some of us thought there
were better ways.  I think one reply was probably that it didn't
belong in ping_pong.   Also, Michael pointed out another way using
existing ping_pong functionality.

However, I think your patch creates a very obvious way of testing
byte-range locks and we should think about how it can be cleaned
up and pushed.

You probably need to clean up the repetitive usage checking...  :-)

Interested to hear what others think.

peace & happiness,
