Thomas had a more complete piece of code which exercised more paths.
The document just has to point to where that code is.

My thought was to provide a one-stop shop; however,
it may be a separate doc or incorporated in this and referenced by it.

I am only allowed to put kernel patches there by the powers that be. So
this wont fit the criteria. It is hard to believe in these
times my ISP charges me $1/M/month every time i exceed my allocated 5M
quota. I have been with this ISP for > 10 years, hence migration gets
harder - and given that many years on the same account, even my .bashrc
approaches 5M ;->
