Actually, POSIX requires it, too.  I implemented a newgrp(1) almost a year 
ago for NetBSD, and forwarded it on to JT (so he could play Standards Cop 
with it).  It's been more-or-less put on the shelf because some other 
things had higher priority.  I do plan, however, on committing it to 
NetBSD very shortly after 1.2 is released.
