      Description

      We've seen a number of bugs in the fair share scheduler not caught by its unit tests, which are heavily mock-based. This JIRA is to add an integration/system/stress test for the fairshare scheduler. This test can help identify races and deadlocks, and when run within the jcarder framework has identified several potential deadlocks for us that aren't turned up running small scale testing.
