But then there should be an active loop which polls the refcounts. The problem
is that when source element has pushed all its buffers out it can't do anything
until a free buffer is available. So it needs to wait for the buffer to get
released. If we had a weak ref notification callback, I wouldn't need to write
a busy loop for it.
