    2626Given the buffering should happened in spawned worker process and we basically only use the `TestResult` provided to `ParallelTestSuite.run` for replicating the events sent from the pool in the main process and there's no test output to capture on the main process (no tests are run in the main process) a potential solution could be to simply disable `buffer` on the accumulator test result.
