Hi Larry,
Is that because the pages have been dirty for so long they've reached
the VM-writeback timeout even though there's no pressure to use them for
something else? Or has that been lengthened because you don't fear
power loss wiping volatile RAM?

So OOM code
kills a (random) process in hopes of freeing up some
pages but if this process is stuck in diskIO, nothing can be freed
and everything grinds to a halt.
Yep, exactly.
