For Xen suspend/resume, I'd like to use the freezer to get all threads into a known consistent state (where, specifically, they don't have any outstanding pagetable updates pending). In other words, the freezer as it currently stands is what I want, modulo some of these issues where it gets caught up unexpectedly. If threads end up getting frozen anywhere preempt isn't explicitly disabled, it wouldn't work for me.
