    Do you really think this makes a measurable difference in execution speed?

Felix, you wimp. We don't make these optimisations because they have a
measurable difference. We make them because it is *physically painful* to
leave those extra cycles laying there. Because we could not face ourselves in
the morning with the self-knowledge that we had turned around and simply
strolled away.

Get with the program, Son.
