           Summary: Return memory more aggressively when large amount of
                    memory has been freed
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mjs at apple.com


At the end of the Mozilla membuster test, FastMalloc has around 90M that is
returnable to the system but hasn't been. We normally limit aggressiveness of
our memory returning to avoid performance degradation. But we might be able to
track when a very large amount of memory has been freed and scavange more
aggressively in such cases only.
