The old behavior (read full blocks) might be useful in other - contexts, so it is still available within the driver as a configuration option. - * Implement poll() and select() support for TCP/IP sockets - * Fixed an important bug in the TCP/IP buffering logic.

The size of the backlog is specified by the - second argument of the standard listen() API. Hooks are provided to support poll()/select() - waiting for connections, with a subsequent call to accept() to use the backlogged connection. - * Fixed a minor bug in accept().
