This patch is really small, and sometimes there's an interest in
avoiding premature _pessimization_. That is, it's nice to avoid making
an operation that seemingly should be fast pathologically slow,
because when someone later runs into the slowness, they're going to
jump through hoops and write really ugly workarounds for the problem
rather than fixing it...
