Replying here instead of on the patch 3 thread (and I'm sorry for mixing up function names there): By saying "for a short period of time only", do you imply without ever getting scheduled on the new (temporary) CPU? If so, I think I understand this change now, but then this could do with saying here. If not, I'm afraid I'm still lost. Jan
