57 Each active process in the system is uniquely identified by a non-negative

161 When a process executes a new file, the effective user ID is set
162 to the owner of the file if the file is set-user-ID, and the effective
163 group ID
165 is set to the group of the file if the file is set-group-ID.
166 The effective user ID of the process is then recorded as the saved set-user-ID,
