It was possible to cause a kernel panic in the send code by initializing an already-initialized mutex, if a record was created with type DATA, destroyed with a different type (bypassing the mutex_destroy call) and then re-allocated as a DATA record again. We tweak the logic to not change the type of a record once it has been created, avoiding the issue.
