Actually, I'm able to spawn new threads perfectly well. The problem is that I can't (?) use performSelectorOnMainThread: because I'm not an NSApplication, and so I don't get the default "main" thread that loops for user input...
You don't need an NSApplication; all you need is an NSRunLoop on the main thread.
To get one, you should structure your main thread's code like
... initialization ...
[[NSRunLoop currentRunLoop] run];
... teardown ...
The runloop call will cause the thread to block and repeatedly wait
for and then handle events, until there are no more runloop sources.
Runloop sources are things like NSTimers and the various -
performSelector... utilities declared in NSRunLoop and NSThread
("after delay", "on main thread", etc.)
If you know exactly when to quit and don't want to deal with removing all runloop sources, you can just call exit(0) at the point where you want to exit (after any necessary cleanup.)
