Thanks, I should add that efficiency is not my objective with these tests.
I'd like the outcomes to include pkg upgrade tips for end users who, for
various reasons, find themselves with the benefits of ZFS (not least,
bectl for boot environments) on systems that are constrained (e.g. 4 GB
memory and limited free space on a HDD).
I sense that vm.pageout_oom_seq might be the sanest approach, in cases
where hardware constraints are relatively severe. I'm open to
alternative suggestions.
In the past I could be quite careless about untimely interruptions to
upgrades ("simply re-run the pkg command, maybe more than once, until it
found nothing more to upgrade."). Nowadays there's a greater risk of an
awkward problem following an untimely interruption. I don't mind the
awkwardness (I know how to dig myself out of a hole); other users might
be less forgiving.
