Same issue here on releng/13.3, on i7-7820HQ with 64G RAM. But there's a
difference as well -- my machine even freezes completely while arc_prune+vnlru
eating CPU.
If I run 9 jobs -- freeze duration is like tens of minutes, but even with a
single job machine freezes for a ~minute at some points of poudriere build.
