I reduced the swapspace back to 1 GB. It's only ever really hit during 
builds.

I set
   vm.pageout_oom_seq=120
   vm.pfault_oom_attempts=-1

There was no improvement. I still see processes getting killed due
to no swap space despite only 7-8 MB being reported used.  It sorta
feels like it's not really able to use swap at all.

Note that everything worked fine on 11.x, this is a new issue on 12.
