--- Comment #20 from Guy Helmer <ghelmer@FreeBSD.org> ---
(In reply to Luiz Otavio O Souza,+55 (14) 99772-1255 from comment #19)

The hold/store/free buffer sharing two buffers in BPF has been a source of
trouble. Should there be a third buffer in BPF so we don't have to wait for
access to a buffer in bpfread()? It would waste memory but seems like it could
cleanly resolve some problems.
