    1.  When writing to a TCP socket, write everything you have to write
        with one "send" or "write" operation if at all possible.
        Don't write a little at a time.  That results in sending small
        packets, because sockets are "flushed" after each write.

    2.  Wait for input from multiple sources by using "select".  (But
        be aware that "select" doesn't work for Windows pipes.)
