Under Linux, this allows users to tune the time (in seconds) to defer connections before allowing them to be accepted. The behavior of TCP_DEFER_ACCEPT changed with Linux 2.6.32 and idle connections may still be accept()-ed after the specified value in seconds. A small value of '1' remains the default for Unicorn as Unicorn does not worry about slow clients. Higher values provide better DoS protection for Rainbows! but also increases kernel memory usage. Allowing "dataready" for FreeBSD accept filters will allow SSL sockets to be used in the future for HTTPS, too.
