assume datagram semantics: when using SOCK_STREAM, if perfused sends frames faster than the filesystem consumes them, it will grab multiple frames at once and discard anything beyond the first one. For now the code can work both with SOCK_DGRAM and SOCK_STREAM, but SOCK_STREAM support will probably have to be removed for the sake of readability. - Remeber to sync parent directories when moving a node - In debug output, display the requeue type (readdir, write, etc...)
