One other note. #2 is conceptually a related group of #4's, so I think it's name should reflect that. (It's view as a group of #4's is more important than as being a part of #1.) So, if you go with lwp (yuck) for #4, #2 should be lwpgrp or some such. I still think lwp's overloaded nomenclature is a reason to stay away from it. *shrug* -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
