            Bug ID: 230143
           Summary: [bmalloc] Merge large frees after making them eligible
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: bmalloc
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: Basuke.Suzuki at sony.com
                CC: ggaren at apple.com

Current implementation tries merging of two mergeable large frees when free is added to largeMap. If one is not eligible, that region is no chance to be merged with other regions in the map. It is possible to improve the chance of merging after all regions are marked as eligible.
