It can return 1, meaning that there's one transfer "alive" that hasn't
completed yet. There's no real definition for "alive" other than that the
transfer has not reached its end state.

It can also return 0, as if the transfer is already completed. Like for
example it hit an error condition really early and just bailed out.

It cannot be 0 and still have an unfinished transfer in there.
