Our issues haven't been addressed because we've given no indication as
to how they can be addressed. For better or worse, our runtime
powermanagement story isn't sufficient to satisfy Google's usecases.
That would be fine, if we could tell them what changes needed to be made
to satisfy their usecases. The Android people have said that they don't
see a cleaner way of doing this. Are we seriously saying that they
should prove themselves wrong, and if they can't they don't get their
code in the kernel? This seems... problematic.
