(In reply to Mark Millard from comment #2)

I should have noted: if a process stays runnable,
FreeBSD does not stop it and swap it out but
instead just pages it. (For FreeBSD, swapping
basically seems to mean that the kernel stacks
were also moved out to swap space and would have
to be brought back in for the process to run.)

Thus, 1 or more processes that use large amounts
of memory relative to the RAM size but also stay
runnable, are not not stopped and swapped out to
make room. In such a context, if free RAM stays
low, despite other efforts to gain some back,
processses are then killed instead.

vm.pageout_oom_seq controls how many attempts are
made to gain more free RAM before the kills start.
