Safe NSArray access

Question
I expected objectAtIndex:
to return a retained and autoreleased object for my use, but my tests with autorelease pools indicate they do not.
This being the case, how do I protect myself against another thread removing an object from an array after I retrieve its reference using objectAtIndex but before I have a chance to use or retain that reference?
Solution
Synchronize access to the array, as you should any access to resources shared across threads.
