On 10.1 this cache eat all free mem and all system freeze, if swap not enabled.

Now is better, but disk cache still cause swap usage or freezes (but less then
on 10x) if no swap present.

Disk cache should have very low priority and be like free mem - avaible to use
by any app for mem alloc or have very hard limit via sysctl and does not
consume all free mem.

Another thing: I do not want use swap, but I need kernel coredumps, how can I
do this?
