SVN commit 825688 by orlovich:

Fix a bunch of bugs in iframe notification that showed up on hosted SunSpider:
1) Be careful to only create a name for frames once, so we can associate its
ChildFrame with it, and know when it's completed, etc.

2) Always let requestFrame (via computeContent) handle the frame navigation since that
handles mimetype changes properly

3) Be careful to not destroy the widget (and hence the part) improperly.
