While this approach could be made to work, it's ugly in other ways.
After wakeup, userspace has to pause for a while before it can trigger
another sleep in order to give all the apps an opportunity to check for
wakeup events and block suspend if they wish to. That's additional
runtime that doesn't exist in the kernel-mediated case.
