            Bug ID: 286985
           Summary: Make JSTests/stress/recursive-try-catch.js less flaky.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mark.lam at apple.com

The JSTests/stress/recursive-try-catch.js test checks that heap usage does exceed an expected max heap.  However, GC concurrency means that this requirement cannot be guaranteed.  This test was also introduced many years ago before concurrent GC became available.  As a result, depending on GC thread scheduling, there's a chance that the test may fail this check.  The only way to ensure that this test passes reliably is to require that the test is run with --useConcurrentGC=0.
