Anybody else remember the speedup loop.

tl;dr : programmer inserts a large empty loop in a UI, so that in weeks when he achieves nothing, he removes a single zero from the end of the loop counter to speed up things a bit.

I would expect the compiler to get rid of that loop.

The story is from 1990. Nowadays you would probably have to be a little bit more clever. Maybe toss in a volatile variable?
