           Summary: CodeBlock::~CodeBlock takes 1us on average
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal

         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: fpizlo at apple.com

It seems like it takes about 1us to destruct a CodeBlock in Speedometer.  That's crazy.

Maybe this is inherent.  In that case, we should consider parallelizing the destruction.  Maybe we should make it easy to parallelize destruction, for those types that don't have to be tied to thread-unsafe ref counting.
