What seems to happen here is that when DocumentWriter::begin() is called while a load is in progress, setDocument(0) will be called which in turn causes the current document to be destroyed. However, the Document destructor destroys its CachedResourceLoader instance which will cancel all pending loads, but Loader::Host::didFail() tries to ref the Document that's being destroyed. This is what seems to cause the crash.

The proposed patch solves this by cancelling all requests before Document is being destroyed.
