Its in fact very important the VM interferes with scheduling. When a task is
a heavy generator of dirty pages it has to be throttled to get fair use of
disk bandwidth and memory

Similarly its desirable as paging rates increase to ensure that everything
gets some running time to make progress even at the cost of interactivity.
This is something BSD does that we don't. Arguably nowdays its reasonable to
claim you should have enough ram to avoid the total thrash state that BSD
handles this way o course
