 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.)
