Maybe that kind of trick deserves a code comment?

I thought about doing that, but it seemed like the maintenance cost of having the comment there indefinitely wasn't worth the minor performance benefit (a benefit that applies only to typical platforms and when optimization is enabled, facts that'd also probably need to be in the comment). For what it's worth, this stuff is now documented in the bug report....
