Running a Cocoa GUI in a non-main thread

Question

I am having a gui/threading related problem in developing a cocoa user interface. The application is designed like this:

Main Thread (#1): parses arguments, loads pl

Answer 1

Why not reverse the problem? Have the main thread spawn a thread (let's call this the app thread), then block before spawning the GUI. The app thread will parse arguments, load plugins, etc. After it's initialization is done, the app thread will signal the main thread to go ahead and launch the GUI.
