When the pipe handles are created, the security descriptor
	indicates that the handle can be inherited.  However, we do not
	want the server side handles to the pipe to be inherited by the
	child CGI process. If the child CGI does inherit the server
	side handles, then the child may be left around if the server
	closes its handles (e.g. if the http connection is aborted),
	because the child will have a valid copy of handles to both
	sides of the pipes, and no I/O error will occur.  Microsoft
	recommends using DuplicateHandle to turn off the inherit bit
	under NT and Win95.
