My thinking is:

- refcount = any request enables, all consumers must disable before
  resource goes offline

- vote = some kind of majority or first-come-first-served decision and
  consumers could be denied the resource

If the semantics are the same I will be confused... this seems to
be a first-come-first-served scheme so I comprehend it.
