I sometimes seen build runaways when using poudriere to build my
standard set of packages on my Ryzen machine.  I don't think this is a
Ryzen-specific issue since I also see the same on older AMD FX-8320E
machine, but much less frequently there.  It looks like a lost wakeup
issue, but I haven't had a chance to dig into it yet.
