The changes try_to_swap_out() has seen in recent
months indeed have the potential to really disturb
the balance between refill_inactive_scan() and
swap_out() ...

Looking into changing/fixing/... this balance may
have some influence on performance, but now that
aging has been reintroduced tweaking the balance no
longer seems to have the huge influence it had in
2.2.

Having said that, it may be good to re-balance the
VM a bit for 2.4.1...
