Not really, have a look here:

http://developer.apple.com/iphone/library/documentation/Cocoa/Reference/Foundation/Classes/NSAutoreleasePool_Class/Reference/Reference.html

If you are making Cocoa calls outside of the Application Kit’s main thread—for example if you create a Foundation-only application or if you detach a thread—you need to create your own autorelease pool.


That's why I am asking that.
But in any case, I have seen this code and it seems that it should work. I did some preliminary tests and I didn't experience any problems.
I just want to make sure that you are aware of this situation.
