Oh dear. Well Derek, I operate on the assumption that
if someone finds something wrong with what I say,
regardless of my intent, then it's my fault, so I
sincerely apologize for conveying that impression to
you.

Trust me, I'm the prototypical Mr. Niceguy.

FWIW, neither humor nor flippancy nor ever crossed my
mind, nor do I even see where you derive that
impression. No matter. I was entirely serious, and
merely seeking understanding.

There are many mysteries in the world of computing, and
regardless of having worked with this stuff for so many
years, I learn new, *basic* and obvious things every
day of my life. So when I don't understand something I
assume that it's because I'm a moron or missing some
significant piece of information, like "Maybe this guy
knows something about how to run two X processes to the
same tube at once that I never realized?"

This is very interesting and useful. I'll have to try
it tomorrow on my work system (where I'm doing this
project), and will try to digest what it is that's
going on. This is one of those Eureka! experiences ...
I had no idea you could do that. Thanks for teaching me
something. Now I'll go off and learn it right.

  Derek> If I have again misunderstood I apologize.

You have. Apology accepted. Please accept mine for
conveying the misunderstanding in the first place.
