      BUG#59084: rpl_do_grant started to fail on FreeBSD (presumably after BUG#49978)
      Problem: master executed a statement that would fail on slave
      (namely, DROP USER 'create_rout_db'@'localhost').
      Then the test did:
        --let $rpl_only_running_threads= 1
        --source include/rpl_reset.inc
      rpl_reset.inc calls rpl_sync.inc, which first checks which of
      the threads are running and then syncs those threads that are
      running. If the SQL thread fails after the check, the sync will
      fail. So there was a race in the test and it failed on some
      slow hosts.
      Fix: Don't replicate the failing statement.
