Indeed the PM can try to send a RM_ADDR over a msk without acquiring first the msk socket lock.
The bugged code-path comes from an early optimization: when there are no subflows, the PM should (usually) not send RM_ADDR notifications.
The above statement is incorrect, as without locks another process could concur ---truncated---
