            Bug ID: 196066
           Summary: [JSC] Property replacing watchpoints should be rarely
                    created in non-JIT mode
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ysuzuki at apple.com

They should be just used for XXXPrototype's toString etc.
We should not create these watchpoints in normal put_by_id etc. if we are in non-JIT mode.
They allocates StructureRareData and HashTable, but these information is not leveraged in non-JIT mode basically.
