* worker and the database has already been shutdown, that there is no crash
* when the owning page gets cleaned up which causes the termination of the
* worker which in turn garbage collects during its shutdown.
*
* We do the IndexedDB stuff in the iframe so we can kill it as part of our
* test. Doing it out here is no good.
