Concurrent NSOperation

I'm writing an NSOperation subclass which completes it's work 
asynchronously. As such I'm going to have to write a concurrent 
operation.

The problem I have is that I don't want to have to setup my own 
'runtime environment', quoted from the docs:

"In your start method, you must prepare the operation for execution, 
which includes preparing the runtime environment for your operation. 
(For example, if you wanted to create a thread yourself, you would do 
it here.) Once your runtime environment is established, you can call 
any methods or functions you want to subsequently start your 
operation. Your implementation of the start method should not invoke 
super."

I simply need to mark the operation as complete when it receives an 
NSNotification. I could setup a thread but that seems a little 
pointless since that NSOperation is supposed to handle it automatically.
