Explicitly terminate runs of aux data blocks with a well-known "aux data terminal" event. Previously a null byte was used. Each aux data block would write the null. Subsequent blocks would overwrite the prior block's null, effectively pushing the null to the end of a run aux data. However, if a different event was traced in the middle of the run it too would overwrite the null and corrupt the stream. With an explicit terminal event, structure can be recovered regardless of any multiplexing.
