/*

* This tests ensures that if the last live reference to a Blob is on the
|
|
|
|
|
* 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.
