OS-level threads don't work because Ruby doesn't support them, and  
ruby threads don't work reliably because of unpleasant interactions  
with the ObjC exception handling mechanism.

I made a patch to ruby and rubycocoa a while ago that attempts to  
work around the latter problem - i.e., it lets you use Ruby threads  
in a RubyCocoa application.

If you're able to recompile both ruby and rubycocoa, you could give  
it a shot. It's still necessary to make AppKit calls on the main  
thread (use self.performSelector...), but you can do ruby-level  
background tasks ok. I've attached the two patches - one to  
ruby-1.8.2 and one to RubyCocoa.
