I'm still missing what the exact "bug fix" is here. So far we have
established that (a) the n_backends count is not tracked by the
collector; (b) the collector does not need it; (c) the count is
recomputed by each backend that might need it; and (d) we could probably
save some cycles by letting the collector count active backends instead
of making the backends do it.
(d) is a performance bug, but if there is a functionality bug I'm not
seeing it.
