AFAIU that means "I'm splitting one object over multiple messages". 99% of the time the right thing to do is change what we consider to be "an object" rather than do F_MULTI. In theory user space should re-constitute all the NLM_F_MULTI messages into as single object, which none of YNL does today :(
