 From my opinion, I am doubting that read-write unionfs works
stably and correctly even on heavy situations. JIMO, current
implementation of nullfs essentially has unstable seen while
heavy read-write situations.

If you want to use nullfs, read-only mode is better even for
heavy situation :)

Thanks
