I mean, easier for CPU :-) The division operation reasonably seems to be more complex than bitwise AND. And since this function is pretty hot it can save a bit of performance. (Actually that's just my assumption. I did not make benchmark really.) Side thought: I suspect some advanced CPUs can optimize such kind of divisions by powers of 2 by themselves.
