Since we don't cycle collect contexts that are not on the main thread.

We found this while running the test in bug 531225. Bent says this causes crashes (I killed it before it crashed).

+    static inline JSBool IsMainThreadContext(JSContext *cx)
+    {
+        return cx->thread == sMainJSThread;
+    }

We already have IsMainThread(JSContext *cx), maybe just use that? :)

sr=jst with that.

Peter, any chance for QA to test this fix with a 3.5.8pre build? Do we have automated tests which cover code lines around the given patch and we can trust?
