The document you read is either wrong or misleading.  On Linux (and
many other POSIX systems) you can set O_NONBLOCK on a socket's file
descriptor using fcntl().  You can also achieve something similar
using ioctl() and the FIONBIO flag.  Anyways, when you combine this
with epoll (Linux) / kqueue (*BSD) you can effectively do asynchronous
socket I/O.
