__task_wakeup() takes care of a small race that exists between threads, but it uses a store barrier that is not sufficient since apparently the state read after clearing the leaf_p pointer sometimes is incorrect. This results in missed wakeups between threads competing at a high rate. Let's use a full barrier instead to serialize the operations. This may be backported to 1.9 though it's extremely unlikely that this bug will ever manifest itself there.
