The answer appears to be that when root quits openwin, it does not remove
the files
/tmp/.X11-pipe
/tmp/.X11-unix
Removing these files or making them world-writeable does the trick.  
Says Val: "This is a known bug (i don't remember the bugID) but you can
find it in SunSOLVE."

orig> After patching several machines, we've noticed strange behavior.

orig> 
orig> 
orig>    # cd /devices/pseudo
orig>    # ls -l clone@0:tcp tl@0*
orig>    crw-rw-rw-   1 root     sys       11, 42 Feb 15 17:11 clone@0:tcp

orig>    crw-rw-rw-   1 root     sys      105,  1 Feb 15 17:11 tl@0:ticotsord

orig> Which I did, but the problem persists.  After rebooting, anyone can log on
