None of it. The work on multiprocess Firefox is primarily an issue in the front end UI code (written in JS), and does not have much to do with networking or crypto. Another thing to keep in mind is that patch notes are a list of user-facing changes, not a breakdown of where the engineering effort went in a particular 5 week release cycle. Removing the command line flag probably took an engineer an hour or two to do. In the same time frame, I spent weeks analyzing and fixing a variety of leaks that only show up in multiprocess Firefox, but none of that shows up in the patch notes.
