Well, if nothing else, this thread can be used as an example of how not
to write programs! I admit, I did not think much when I wrote that
example function, partially because I was really surprised by the
*large* time gap in the results. Not saying that if I did think that
would've changed anything :-(
Oh well. At least we've justified the loops completely now. And pulled
