Nothing comes to my mind that requires that the Lisp thread be the initial thread; I would think we could start a new thread for the main Lisp interpreter. (At least in the X11 build, that should be fairly easily testable, too — just move *everything* we do from the initial thread to a new thread, and have the initial thread just wait around doing nothing.) But if there are toolkits or libraries besides Cocoa that also insist on running in the main thread, they may not be able to coexist in use in one process, unless we manage the main event loop ourselves, or tell one GUI event handler how to recognize when another has activity that we need to mediate some callbacks for.

It might not be a bad way to go, if we can keep the interprocess communication efficient enough, but I don’t think it’ll be required. Even if we do that, some part of the main Emacs process needs to communicate with these multiple GUI processes, so do we wind up with multiple UI threads in the main process anyway?
