I thought we (linux community and Android) where ok with the plist /
pm-qos implementation of the building blocks needed to implement the
suspend blocker feature on top of a pm-qos request class (I think the
name was "interactive") pretty much the exact same symantecs as the
suspend blocker thing, just with pm-qos kernel api's.

I'd rather see the re-tooling of pmqos happen.
