I think it is you who is confused. For power management purposes suspend
is nothing more but a deep idle state.

(and please don't mention @#$@ up x86 ACPI again, Intel knows, they're
fixing it, get over it already).

So you're going to sprinkle this suspend blocker shite all over regular
userspace? Why not instead work on getting apps to behave properly and
idle when there's nothing to do?

After all, if you have the code to add suspend blockers into, you also
have the means to fix it being stupid in the first place.
