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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
