           Summary: [V8] WebKit sends unnecessary low memory notification
                    when running memory benchmarks
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore JavaScript
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ulan at chromium.org


In the following benchmark, we get GC pause of about 15 seconds because of low memory notification that was sent from WebKit.

In this case the low memory notification is unnecessary because all memory usage consists of V8 objects, not DOM objects. So in this case V8 can schedule GC itself more optimally.
