    Description

      See https://github.com/apache/arrow/pull/6160/checks?check_run_id=384146741#step:5:1556 for example

      [ RUN      ] TestSlowInputStream.Basics
      /arrow/cpp/src/arrow/io/memory_test.cc:308: Failure
      Expected: (dt) < (latency * 3), actual: 4.96068 vs 1.8
      [  FAILED  ] TestSlowInputStream.Basics (4961 ms)
      [----------] 1 test from TestSlowInputStream (4961 ms total)
      

      Tests that rely on timing are pretty tough to do on public CI. We should consider moving this somewhere that doesn't run on CI.
