[jira] [Created] (ARROW-13173) [C++] TestAsyncUtil.ReadaheadFailed asserts occasionally

Yibo Cai created ARROW-13173:
--------------------------------

             Summary: [C++] TestAsyncUtil.ReadaheadFailed asserts occasionally 
                 Key: ARROW-13173
                 URL: https://issues.apache.org/jira/browse/ARROW-13173
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
    Affects Versions: 4.0.1, 4.0.0
            Reporter: Yibo Cai


Observed one test case failure from Travis CI arm64 job.
https://travis-ci.com/github/apache/arrow/jobs/518630381#L2271

{{TestAsyncUtil.ReadaheadFailed}} asserted at https://github.com/apache/arrow/blob/master/cpp/src/arrow/util/async_generator_test.cc#L1131

Looks _SleepABit()_ cannot guarantee that _finished_ will be set in time, especially on busy CI hosts where many jobs share one machine.
