Konstantin Belousov c1344d2bbe 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.
