There's no special mention in the method docs, because none is needed - the
general rules apply to this method as-is.

If the array calls -copy on the items that you've added, then *it* is
responsible for balancing that -copy, *not you* - just like always. You
didn't send the -copy message, so you are not responsible for balancing it.
The inside of another object is Las Vegas - what happens there, stays there.
Trying to balance code other than your own is what gets a lot of newbies
into deep confusion.
