As far as I can tell, these fence_ptr s that get polled are not packaged into a fence obj, and in practice I see 10s of seconds wait before these timeout and reset can begin. Also after reset there is often a long wait, up to 2 minutes, for all the tlb_fence_work to timeout (not addressed by this patch, still haven't figure out what's going on there)
