I tried toying with it over a circuit with some propagation latency (20ms 
in this case, which I suspect was never tested :P) and all it did was make 
the remote side think link had flapped every time you did a commit on 
either end. :)

But at any rate, yes even working LFM is pretty worthless right now. Also 
8.3 seems to add some 802.1ag CFM configuration options, though it isn't 
documented in the release notes, and I don't think its offically supported 
until 8.4 anyways.
