Ok, I tested several runs and the problem didn't manifest. Additionally
I tested that wraparound also worked on at least some cases, by doing
pg_resetxlog -O 4294967200 $PGDATA
dd if=/dev/zero of=$PGDATA/pg_multixact/members/FFFF bs=8192 count=32
and retrying the test. I did this several times, with no problems
detected.
