You haven't really explained this and I have asked several times IIRC.
Why do you even need to do those batches? Why cannot you simply relly on
the memory pressure triggering the memory reclaim? Do you have any
actual numbers showing that being pro-active results in smaller
latencies or anything that would show this is actually needed?
