It looks like one of the issues that contributes to non-ZFS contexts
seeing process-kills for out-of-swap when there is plenty left has
been identified in the code for head. See:

https://lists.freebsd.org/pipermail/svn-src-head/2018-April/111629.html

It looks like Mark Johnston will be checking something in to help
but there is more to do after that for what was identified.


Overall about the reporting:

Despite lots of hypothesizing beyond the evidence presented, I'm glad for
the reports of issues from multiple types of environments and to known of
types of contexts multiple folks have seen somewhat similar problems with.
Separating issues out can be difficult and time consuming. Knowing what
all needs eventual coverage helps guide things as progress is made. This
is true even for those that are just looking to pick up the eventual
fix(es) for the problem(s) they happen to have run into.
