If you think the code does not work when the system frequently suspends
and resumes, then well it is broken already, as that can happen just
as much on non-Android systems.  So maybe we should just remove it if
it is so broken that you fear about regressions on the 3 and a half
Android systems in the world running an upstream kernel?
