You have to be careful with signals, as they are not blocking, I mean:
user clicks suspend
upower sends Suspending()
pc is sleeping
upower sends Awakening()
Applications get time to process the Suspending signal call.
Applications get time to process the Awakening signal call.
So you get a nice race.
