So, this bi_pool overriding caller specified custom bi_destructor is
rather unusual. I know why it's like that - the patch series is
gradually replacing bi_destructor with bi_pool and removes
bi_destructor eventually, but it would be far better if at least patch
description says why this is unusual like this.

Thanks.
