Similar as "Should watch UPower AboutToSleep signal",
https://bugs.freedesktop.org/show_bug.cgi?id=28370 , telepathy mission control
should watch systemd signals / create inhibitor locks for suspend.

On my system, current Chakra, the UPower AboutToSleep Signal isn't sent anymore
as it has completely transitioned to systemd. This results in telepathy not
being able to log out prior to suspend, and because XEP-0198 is not implemented
in telepathy, I stay online for others in my contact list until the server
disconnects me according to his TCP Keepalive settings, which defaults to 4
hours on Debian systems.

During that time, all messages sent to me are getting lost without any notice
for the sender's or the receiver's side.

I could reproduce this with the KDE-Version of Fedora using KTelepathy like on
my own system.


Information on the way systemd handles this:
http://www.freedesktop.org/wiki/Software/systemd/logind/

Unlike UPower, Systemd doesn't just spit out a signal and waits a second and
then shuts down, one can create something called inhibitor locks, which one
cand hold and release when one is done with cleaning up. No general one second
until everything is suspended, but exactly the time everything needs.
Disadvandage is more implementation effort than just listening to a signal.

Implementation in NetworkManager:
