The PolicyKit docs have some:

That's a good question - I think with system activation by default
activated mechanisms will stay around, though obviously the kernel can
page them out.  The clock applet mechanism
(http://svn.gnome.org/svn/gnome-panel/trunk/applets/clock/gnome-clock-applet-mechanism.c)
has its own 30-second timeout but it's kind of a hack.  It's something
we should look at addressing - unfortunately just calling exit() after
30 seconds I believe creates race conditions, and to fix it correctly
will need special DBus support.  There was a thread a while ago about
this on the DBus list IIRC.
