Notes on the crash:
* The assert at JavaScriptCore/runtime/Collector.cpp:199 isn't too useful, so
it is good to comment it out (I think there may be a bug in the counting done
in that function of num live objects.)  

* Use r51657 for repros. I couldn't repro with tip of tree,  r51782 had build
errors for me, r51657 built and repros.

* The smallest repro that I got so far is two test:
   run-webkit-tests  --iterations 20 LayoutTests/fast/websockets/
fast/workers/dedicated-worker-lifecycle.html 

  If you run ~20 times, you'll very likely see the crash.

* Running with malloc guard causes the test to time out but if you turn off the
brute force gc in worker-util.js, the test will pass (and the above crashes
were done like this).

* It turns out that the crash was due to WebSockets and was recently fixed with
https://bugs.webkit.org/show_bug.cgi?id=32226 in r51790. (Note no more buildbot
crashes have been listed after that revision).

Case closed for the crashes!
