What if I used NSInvocationOperation like this:
NSInvocationOperation *myOperation = [[NSInvocationOperation alloc]
initWithTarget:self
selector:@selector(doResourceHungryTask) object:nil];
[operationQueue addOperation:myOperation];
"doResourceHungryTask" would be a method in my delegate class. Would I still
need to lock/unlock (I'm modifying the class's properties from itself, not
another class)? I'm not sure on the exact workings of NSInvocationOperation, I
just found out about it.
