* DocumentChannel is a protocol agnostic placeholder nsIChannel implementation
* that we use so that nsDocShell knows about a connecting load. It transfers
* all data into a DocumentLoadListener (running in the parent process), which
* will create the real channel for the connection, and decide which process to
* load the resulting document in. If the document is to be loaded in the
* current process, then we'll synthesize a redirect replacing this placeholder
* channel with the real one, otherwise the originating docshell will be removed
* during the process switch.
