  New Revision: 50518


    ext/socket/init.c: use SOCK_NONBLOCK if available
    This saves a system call by allowing us to use SOCK_NONBLOCK in
    Linux when accept4 is available.
    Note: I do not agree accept_nonblock should always make accepted
    sockets non-blocking, and will propose a future API to allow
    controlling whether accepted sockets are non-blocking or not
    regardless of how they were created.
    * ext/socket/init.c (cloexec_accept): support nonblock flag and
      use SOCK_NONBLOCK if possible
    * ext/socket/init.c (rsock_s_accept_nonblock): update cloexec_accept call
    * ext/socket/init.c (accept_blocking): ditto for blocking
    * test/socket/test_nonblock.rb: check nonblock? on accepted socket
      [Feature #11138]
