The module is a dummy to be filled in later Other structural changes to sesexec:- 1) A failure of sesman needs to be detected and handled without causing sesexec to exit 2) If sesexec exits, the session can never be rediscovered. sesexec must be robust enough to stay up for the lifetime of the session so that the discovery function always works. 3) There is a mechanism for sesexec to terminate the session, but it doesn't work, as SIGCHLD is not processed while we are waiting for the session to finish. This needs fixing.
