kib 21fe622aa6 Prevent some parallel swap-ins, rate-limit swapper swap-ins. ... If faultin() was called outside swapper (from PHOLD()), do not allow swapper to initiate additional swap-ins. Swapper' initiated swap-ins are serialized because they are synchronous and executed in the context of the thread0. With the added limitation, we only allow parallel swap-ins from PHOLD(), which is up to PHOLD() users to manage, usually they do not need to. Rate-limit swapper' swap-ins to one in the MAXSLP / 2 seconds interval, counting faultin() swapins.
