           Summary: WebProcess can get stuck in GC during many low memory
                    signals
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: slewis at apple.com


We have seen evidence of a computer getting stuck in GC during a low memory signal.  The GC was paging in more memory to run and so it was unable to finish before the next low memory signal fired.

We think with the new style of GC we will not get any value to forcing GC during a low memory signal so we should remove the call.
