The first oom from that night attached.  Note, the oom wasn't as dire
with your mhocko/4.9.0+ as it usually is with stock 4.8.x: my oom
detector and reboot script was able to do its thing cleanly before the
system became unusable.

I'll await further instructions and test right away.  Maybe I'll try a
few tuning ideas until then.  Thanks!

I think my PAE-slow-IO bug started way back in Fedora 22 (4.0?), hard
to know exactly when as I didn't discover the bug for maybe a year as I
didn't realize IO was the problem right away.  Too late to bisect that
one, I guess.  I guess it's not related so we can ignore my tangent!

You're for sure right that the IO-slow bug was definitely worse the more
ram was in a system!  (The mem=4G really helps alleviate this bug and is
good enough for me.)

Completely off-topic: it would be great if rather than pretending PAE
should work with large RAM (which seems more broken every day), the
kernel guys put out an officially stated policy of a maximum RAM you
can use, and try to have the kernel behave for <= that size, and then
people could use more RAM but clearly "at your own risk, don't bug us
about problems!".  Other than a few posts about Linus hating it,
there's nothing official I can find about it in documentation, etc.  It
gives the (mis)impression that it's perfectly fine to run PAE on a
zillion GB modern system.  Then we later learn the hard way :-)
