[jira] [Created] (ARROW-18383) [C++] Avoid global variables for thread pools and at-fork handlers

Antoine Pitrou created ARROW-18383:
--------------------------------------

             Summary: [C++] Avoid global variables for thread pools and at-fork handlers
                 Key: ARROW-18383
                 URL: https://issues.apache.org/jira/browse/ARROW-18383
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Antoine Pitrou
            Assignee: Antoine Pitrou
             Fix For: 11.0.0


Investigation revealed an issue where the global IO thread pool could be constructed before the at-fork handler internal state. The IO thread pool, created on library load, would register an at-fork handler; then, the at-fork handler state would be initialized and clobber the handler registered just before.
