It's one of Don Vonada's laws.
Ah, thank you, thank you, that's the one I was looking for!
I knew _you_'d know it! :-)
A related one ... came from Professor M. V. Wilkes
That one I _did_ remember (although I couldn't remember if it was Wilkes or
Wheeler - I knew it was one of those Cambridge guys :-), but it's not quite
as pithy as the Vonada one.
