It does to me

some options:

- You override the acquire, release and stop methods and take a buffer from
  your own queue/array/whatever you use to implement the pool. We need to make
  do_alloc_buffer() public.

- Implement a method to iterate the queue buffers to filter out a buffer that
  you want.

What exactly would you want to do with the buffers from atomic queue?
