another thought:
would it help if we extended the 'soft lockup watchdog' with periodic
'try whether the whole system can be frozen' checks? That would make
testing coverage alot wider, and it would also give kernel developers an
easy way to make sure the kernel is still freezable. (instead of having
to try something like sw-suspend explicitly)
