i.e. the kernel workers are doing the same work. They aren't being
killed sooner as a result of logging out from the DE. The only
apparent change from logging out from the DE from which the scrub was
issued, is the btrfs process becomes status Z. It is in fact not being
killed, which itself is kinda interesting/unexpected.
