Indeed, we could either have some reference count in the timer to
disable it when there's no buffer that needs it, or keep it running at
all times.

Of course, if this is deemed too complicated, I guess we could go with
your original proposal, but in that case we should at least have some
comment there explaining why this mode is so different from others.

Thanks.
