How would you qualify a "last ditch" trigger?
Would this be called from "standard" vm_lowmem look or would there be some extra
check for even more severe memory condition?

turn and flushes some or all of the buckets in per-cpu caches. Presently that is
not done due to synchronization issues. It can't be done from a central place.
It could be done with a callout mechanism or a for loop that binds to each core
