[This is extracted from another context that
involved the Pine64+ 2GB.]

As of updating to -r337400 the Pine64+ 2GB no
longer will boot from the e.MMC on the microsd
adapter card. (I switched to tracking fully
modern dts use, u-boot, etc.)

So I tried a build via a USB SSD as the root
file system and swap partition. As reported in:

https://lists.freebsd.org/pipermail/freebsd-arm/2018-August/018605.html

it failed with an Out Of Memory kill. (More detail there.
I did not adjust vm.pageout_oom_seq .)

This should have avoided I/O latency problems being
involved. (That message is part of a long on-going
thread tied to OOM kills, most of the reports involving
large I/O latencies being involved.)

Very little swap was observed to be in use. This was
a context with Mark Johnston's reporting patches in
place, but they only reported the kill itself, not
waiting for I/O or such.

I can not change the Affects Only Me status.

Dimitry Andric is possibly the wrong assignee:
not the compiler's problem if the system did an
Out Of Memory kill of a process.

Other bugzilla's are: 227609 230402, not just this
230454.
