    Description

      TestDrillbitResilience.foreman_runTryEnd() exposes this problem intermittently

      The query fails and the Foreman reports the failure to the client which removes the results listener associated to the failed query.
      Sometimes, a data batch reaches the client after the FAILED state already arrived, the client doesn't handle this properly and the corresponding buffer is never released.

      Making the Foreman wait for all fragments to finish before sending the final state should help avoid such scenarios.
