oh I'm certainly not claiming a 1g default swap is appropriate, that
does seem far, far too small to me and will likely cause widespread
issues beyond just this, I was only saying that tweaking the systemd-
oomd swap % full setting would IMHO not be likely to fix this very well
- and as you point out increasing the swap size to a more reasonable
size almost certainly will help (and might be why upstream hadn't
noticed this before), regardless of the systemd-oomd swap % used default
setting, because it would be far less likely to fill swap up to the oomd
swap % full default.

weird things?

From my quick read of the code, it doesn't seem to be doing anything
weird at all, I think it's doing exactly what it's programmed to do. I
just don't think the code is correct.
