In addition to this approach, we may want the ability to tell WebKit to open up a new WKView with  the source thus avoiding two potential copies of the source over the wire.

Consider factoring common code out of processDidExit() and close().

Maybe keep these sorted?

Considered, but not doing it in this patch.
