Below doc is not correct, because for ConcurrentLinkedDeque and
ConcurrentLinkedQueue, addAll is a atomic operation.
"Additionally, the bulk operations addAll, removeAll, retainAll,
containsAll, equals, and toArray are not guaranteed to be performed
atomically. For example, an iterator operating concurrently with an
addAll operation might view only some of the added elements."
It should be modified as some thing like below:
"Additionally, the bulk operations removeAll, retainAll, containsAll,
equals, and toArray are not guaranteed to be performed atomically."
