I hope so.

No, it is enabled by default.

All these servers are slaves. They don't send notifies.
So while I'm really confused about described issue, I'd like to not
speculate on it, because it happened only once.
What I don't like at all is the impossibility to disable these
lookups. Of course I can follow Jeff's advice and redirect these
lookups to localhost, but it is not a solution, it only transfers
problem to another area.
Ok, may be I'm a paranoid and worrying about trifles, but news about
compiled in hints astonished me.
