This is a good idea, but I am NAKing it regardless.  The advantage really
doesn't matter, and we're adding a compilation difference that may some day be
deprecated, or cause a bug, or something.  It's just not worth it overall.

In the long term I am really hoping snowpatch is something that can run forever,
and maybe someone who doesn't know much about it will have to fix it, and this
may well just ruin their week.
