  37     which launches a single child process which in turn creates

  69     <p><code>AcceptEx()</code> is a Microsoft WinSock v2 API that provides
  70     some performance improvements over the use of the BSD style
  71     <code>accept()</code> API in certain circumstances. Some popular Windows
  72     products, typically virus scanning or virtual private network
  73     packages, have bugs that interfere with the proper operation of
  74     <code>AcceptEx()</code>. If you encounter an error condition like:</p>
