I had the rotors machined on my '74 Toyota Corolla for what
was probably about the third time, and they warped again in about a
month. I opted to live with it until about seven months later when the
vibration had caused enough pad wear that one of the pads slid out of
the caliper... on a hill... with some jerk sideways across the lane in
front of me... Thank God that the emergency brake cable didn't snap.

My advice: make sure that you're brakes work!!! I check the pads about
every six months now, and the brake fluid every one or two. I also
wouldn't worry about the one machining. I'd even have it done twice if
it became necessary. You can check the manual for the minimum
acceptable thikness. Once it gets near this buy new ones! I would
never again drive a car with brakes that weren't perfect. You don't
almost die very many times!

BTW, my mother has an '81 Tercel that had the same problem. She had
the rotors machined at 20,000km (also under warranty) and has had no 
problems since.
