No, I got confused, sorry about that. Your configuration allows bursts
up to 64 seconds long. I guess there's nothing wrong with that.

I already asked Stephen to revert that patch, it was not meant to
be included yet, unfortunately it made it into the release. Even
more unfortunate is that it looks like we need larger types in the
ABI to properly support nano-second resolution.
