>Description:
	Inetd closes file descriptor for the service marked as stream
	and wait, and select without opening again.  As a result, after
	the service exit, select fails repeatedly.

	Also, (child) inetd fails to get client address if stream and
	wait.

>How-To-Repeat:
	For example, enable identd in inetd.conf like this:
ident		stream	tcp	wait	nobody.kmem /usr/libexec/identd	identd -w -t60 -l -o -e -N

	Then, connect to it and watch log file.  Here is output of my
	/var/log/messages file.

>Fix:
	This seems to because inetd is changed to close file descriptor
	just if it is stream (previously, it is closed if stream and nowait).
	But still pass to select after the server exited.

	Just backout changes or reopen file descriptor?
