I'm not sure why, but I had the thought that we already had done that,
and was a bit surprised that it wasn't that way, so +1 from my part.

I do think it'd be good to find a way to check every once in a while
even when we aren't going to delay though.  Not sure what the best
answer there is.

Thanks,
