Well, if user space configures the system to use suspend as a "power off
flavor" and doesn't even try to ensure the filesystems to be synced before
suspending (in that mode), that's on the edge of insanity.

And it falls into the "latent bugs that may be there because we've always
synced before suspending" category in my view.

Thanks,
