Well, to start off with, some stats that could be tracked at the API
level could be common. What about counts of number of enqueues and
dequeues?

I suppose the other way we can look at this is: once we get a few
implementations of the interface, we can look at the provided xstats
values from each one, and see if there is anything common between them.
