Description Alan Amesbury 2003-08-07 00:50:18 UTC 
	Use of the multiuser capabilities of screen (misc/screen in ports)
	fails between multiple users.  A single user can attach to
	sessions owned by that same user, but a different user is
	unable to attach.  The second user's "screen -x ..." command
	hangs, and the first user's screen session indicates the
	error "Attach attempt with bad pid(###)" where ### is the
	PID of the process attempting to attach.

	I'm using the version built right out of the ports tree
	(v1.48 2003/05/04 20:23:34).

Fix: 

No workaround known.  Behavior is NOT found under FreeBSD
	4.8-RELEASE.  A search with Google suggests that this
	problem may have started to manifest itself only since
	FreeBSD 5.0.
How-To-Repeat: 	Create a screen session with the ports default for
	/usr/local/etc/screenrc and the following in ~/.screenrc:

		startup_message off
		multiuser on
		addacl testuser

	Start a screen session.  Log onto the box as "testuser"
	and do a "screen -x user" where "user" is the username
	of the user running screen.
