* Utility function to test window destruction behavior. In general this

|
|
* 1) Create a new iframe

* 2) Create a new DOMRequestHelper

* 3) initDOMRequestHelper(), optionally with weak or strong listeners
|

* 4) Optionally force a garbage collection to reap weak references
|
|
* 5) Destroy the iframe triggering an inner-window-destroyed event
|
|
* 6) Callback with a boolean indicating if DOMRequestHelper.uninit() was
|
|
* called.
|

|

* Example usage:
|
|
*
|
|
* checkWindowDestruction({ messages: ["foo"], gc: true },
|
|
* function(uninitCalled) {
|
|
* // expect uninitCalled === false since GC with only weak refs
