-----------------------------------

             Summary: [C++] Research jemalloc memory page reclamation 
configuration on macOS when background_thread option is unavailable
                 Key: ARROW-6994
                 URL: https://issues.apache.org/jira/browse/ARROW-6994
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney
             Fix For: 1.0.0


In ARROW-6977, this was disabled on macOS, but this will potentially have 
negative performance and memory implications that were intended to have been 
fixed in ARROW-6910
