We call Stash.Unstash() to pop off the oldest message message at the top of the Stash.

But if I understand in correctly, Stash.Stash() specifically doesn't pop off the oldest message - it pops off the last message placed on the stash. To have the "oldest" message (first message placed on the stash) processed first by the actor, you'd have to use UnstashAll(), which preserves the FIFO ordering of the stash.
