could you outline the problem to me? freeze_processes() should be a
generic facility to move all kernel processing into a 'known' context of
execution. All the PF_NOFREEZE kernel threads are supposed to do
periodic calls to try_to_freeze(). They should not (and most of the time
they do not) prevent freezing of all state on the system.

am i misunderstanding the problem?
