Point well taken :)

Just to clarify, my understanding is that when you want to update the UI from 
code that is not on the main thread, you will need to use 
performSelectorOnMainThread. Therefore I created the updateStatus: method to 
ensure the status field is always updated on the main thread, no matter from 
which thread it is being called. 

But in my naivety, I probably overlooked something very basic.

I will do certainly that.
