NullReferenceException when using ExplicitPlacement

There is a bug in LegacyLocalMailbox.Flush(RemoteAddress) that allows two worker threads to execute vertex code (in particular, the VertexInput.Flush() method). This causes unsafe access to the contents of the various message buffers in downstream mailboxes, which can lead to data corruption and crashes.
