           Summary: Create a more generic way for VMEntryScope to notify
                    those interested that it will be destroyed
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: sbarati at apple.com


Currently, when VMEntryScope is destroyed, and it has a flag set that the VM needs recompilation, it calls Debugger::recompileAllJSFunctions.
This is tailored specifically for the Debugger and its purposes of recompiling all functions once the VM stops executing code. 
This patch will substitute this one recompilation flag with a list of callbacks that can all be notified when the VMEntryScope dies. 
This creates a more generalized interface to being notified when VMEntryScope dies.
