That's a reasonable sentiment, but removing background_pgbench() isn't going
to fix 017_shm.pl.  I'm not enthusiastic about any fix that repairs
src/bin/pgbench without repairing 017_shm.pl.  I'm okay with skipping affected
test files on dragonfly >= 6 if you decide to cease figuring out how to make
them pass like the others do.
