js/dom/basic-weakmap.html was flaky for a long time, but starting today, it's failing most of the time (most reproducibly on Gtk and Efl bots, but Mac too).
-PASS (keyLessObjectCount - valueLessObjectCount) > 1500 is true
+FAIL (keyLessObjectCount - valueLessObjectCount) > 1500 should be true. Was false.
All Mac debug builders have one of the last two builds failing because of this test right now.
