We are moving away from short term pinning, and need a way to evict
objects locked by the current context. Pass the ww context to all
eviction functions, so that they can evict objects that are already
locked by the current ww context.
On top of that, this slightly improves ww handling because the locked
objects are marked as locked by the correct ww.
