I find it easier to dismount the saddle and stand with both feet on the ground when I have to stop. I found this video very helpful for developing a smooth technique for stopping, then starting again. Granted, I am a platform pedaler - not sure what additional technique you may have to utilize if you ride clipless.

Starting and Stopping

I have seen fellow cyclists ride in meandering circles in front of cars because they don't want to detach their cleats from their clipless pedals while waiting for the red light. Looks risky to me.
