At least in our case it was a bgp route with a third-party next-hop (server) living on a connected LAN segment.
So we could not be saved by BFD in this case, but i admit its a special setup.

But it is funny that this behavior is present across platforms (M7i to MX with DPC) and junos versions (from 8.0 to 10.4) but this of course may have been coincidence.
