btw, I think it isn't always under the sink's control..  since the refcnt is
incremented before the finalize function is called.  If the finalize function
itself ref's the buffer and puts it in a pool of available buffers which
another thread can pad_alloc from, depending on thread priorities and such, you
could end up returning a buffer from pad_alloc w/ refcnt==2.

but it's also a legit use-case in pipelines with a tee, for example, or other
cases.
