You're right. But for what I need in this particular case it's perfect. It
only has to be unique per node, and only a few million times. I could even
use a counter, but then I'd have to have a process on each node just to own
the counter.

I'll use some combination of make_ref() and now() and it'll be fine. I just
wonder if it isn't a weakness in how phash2 works with refs?
