conformance/context/context-creation-and-destruction.html is failing because we are hitting are 16 context limit.
While the test creates and stops using the contexts (by leaving scope) they are only actually destroyed at the whim on the garbage collector.
We have a lot of room to play with the number of maximum active contexts. For the sake of this test passing I think we should raise the limit to 64.
(or at least 50)
