>Description:
	The close(2) manpage does not list ENOTCONN as a possible error
	return, yet I have just received it.
>How-To-Repeat:
	Not sure.
>Fix:

	It may be relevant to split the ERRORS section into sections:
	generic errors that all fd's can give, and subsystem specific
	errors that can only come from pipes, devices or sockets.
