It has a way to see the problem. Ian not aware of any event loop discussion, it is something I saw when investigating that bug.

I have a plan to do more or less what Gdk does on OSX, use lower level (Core Foundation) API:s. The NS-port has many special things (resizing, redrawing and more) that depends on how things are done now, so it isn't just a replacement of a few functions.
I haven't looked at the Mac port, but if it uses CF for the event loop, code may be reused from there.
The basic concept is to have one thread for file descriptors and let the main thread deal with Cocoa events. The code today does something similar, but it relies on polling each 0.1 second.
