Bug 102758 – [Blackberry] When a frame is being detached, cancel all its network jobs.

• Component: WebKit BlackBerry
• Status: RESOLVED FIXED

[Chris.Guan]

When a frame is being detached, cancel all its network jobs with exception of
PingLoader.

This is a follow-up of RIM PR134207.

Each NetworkJob contains a pointer to Frame. The safety relies on the
assumption that FrameLoader::stopAllLoaders() always cancels all network jobs
that belongs to the frame (except PingLoader, for which we unlink the
NetworkJob from the Frame, so it is safe). If one day that is no longer true,
we are in trouble.

We already maintain the full list of active NetworkJob in the NetworkManager
skeleton. So it is easy to cancel all network jobs that link to the
falling-down Frame if any, or clear their m_frame pointers... At least we
should assert no such NetworkJob exists in debug build.

I like this patch a lot.  I don't think it's worth it to fix the typo in the commit log as a new round of changes.

Typo here - refactor

But you have to fix these.  So you might as well fix the typo too
