Yes overwrite is reasonable. Imagine real-time data like the
accelerometer/magnetometer of a cell phone. The most recent data can
overwrite the oldest because typically the most recent is most
important (ie which way is the phone facing *now*) and then maybe some
recent history data (to detect gestures), but the oldest data can be
thrown away.
