I forgot commenting this bit. This is not true, because I don't want a
low fd to be notified on critical level. The current interface just
can't do that.

However, it *is* possible to make non-strict work on strict if we make
strict default _and_ make reads on memory.pressure_level return
available events. Just do this on app initialization:

for each event in memory.pressure_level; do
	/* register eventfd to be notified on "event" */
done

Then eventfd will always be notified, no matter the event.
