manager.c ?

[grundym us ibm com (grundy)]

Hi Folks -

Federico put a note in http://live.gnome.org/GnomePerformance/LoginTime

"Seems the idle state we are interested in is set in manager.c:1372,
update_save_state(), just after launching all the clients in the
start_list."

Is this the end point that we can use as a marker to stop performance
measurements? If so, does anyone know which source tarball this is part
of? (my apologies for my ignorance, I'm trying to get better with the
code navigation)

Thanks
Mike
