Marked as flakily asserting in <http://trac.webkit.org/r164030>. Looks like all worker tests have regressed last week :-(

I think this is a dup of bug 128537. What is happening is that CodeBlocks from the Worker virtual machine are being marked as part of the main thread's garbage collection, which confuses our ASSERT later on. *** This bug has been marked as a duplicate of bug 128537 ***
