You've missed the big warning somewhere in the docs that most of
AppKit is not threadsafe. Why do you want to create a window on
another thread? What is wrong with doing it on the main thread?
Mike,
Your comment is correct in general, but according to the thread safety
guidelines you're supposed to be able to create windows on background
threads:
<http://developer.apple.com/documentation/Cocoa/Conceptual/Multithreading/ThreadSafetySummary/ThreadSafetySummary.html#//apple_ref/doc/uid/10000057i-CH12-123364

That said, it seems that it's not safe to create views on background
threads, so that's at least one thing that's not right in the few
lines of code that was quoted.
Mattias: You should review the thread safety documentation carefully,
and consider if you're in compliance or not. Note that if something
isn't called out to be safe to use on background threads, you should
assume that it's not. The creation of you UI isn't typically thread
safe, and it's also in general not the type of work that you'd need to
offload to background threads. It's probably better to set up the UI
on the main thread, and only perform work for your underlying data
model in the background - That's likely where you have most need for
computing power in any case.
