My understanding is that this was finally fixed in the GNOME 3.8 cycle:
if you have GNOME Shell 3.8 and logind, and something suspends *via
logind* (including hotkeys, lid-close events and Shell itself), suspend
will be delayed until either the Shell has locked the screen, or some
reasonably long timeout has elapsed. I could be wrong there, though.
If a privileged process suspends not-via-logind (direct use of kernel
interfaces, and perhaps also pm-suspend), then logind doesn't have the
opportunity to enforce that locking. Also, I'm not sure whether
gnome-screensaver, as used in fallback/flashback/whatever it's called
this week, participates in that locking mechanism.
