Shared memory for zygote mind meld
As I mentioned in legacy/trac#6937 (moved), I think we could really use a shared memory mutex as some kind meeting point for various Tor specific applications. This likely would be created by Tor or by a zygote that launches things like Tor and the Tor Browser. In theory, we could then have the launcher application and ensure we don't launch extra copies of Tor, we could ensure that we know how we may connect as well as how to authenticate; lots of stuff becomes possible with a little IPC love.
I have a sketch of the zygote/launcher process but I need to take it from my notepad to text, so I'm merely capturing this part of the process in this ticket. More tickets to come.
