Bingo! That occurred to me when I woke up. As I went to sleep, I was
picturing an elaborate scheme of saving the "last N" vectors, and recycling
them in tricky ways. Overnight, sleep simplified the recycling scheme into
an empty statement <wink>.

Why? Thread problems aren't solved by superstition, and that's what adding
"volatile" *usually* is. It's generally no more of a cure than adding a
sleep(). More on that in my reply to Guido.
