on devpts in Linux has been changed to conform to POSIX. As a result we can no longer assume that the ctime will stay unchanged throughout the life of the session. We store the session ID in the time stamp file so there is a much smaller chance of the time stamp file being reused by a new login. While here, store the uid/gid in the timestamp file too for good measure.
