Interfaces, strings and arrays already work well in multi threaded contexts and ARC will use the same mechanisms here, so there is no need to discuss "parallel" and ARC together. Note: ARC doesn't change that the developer him-/herself needs to make his/her classes threadsafe. ARC only "protects" the references. Regards, Sven
