You must have missed or misinterpreted the "The software should be
running continously for practically forever" part. The problem of
restarting python is not the 200 msec lost but putting at stake
reliability (e.g. for health monitoring devices, avionics, nuclear
reactor controllers, etc.) and robustness (e.g. a computation that
takes weeks of cpu time to complete is interrupted without the
possibility to restart from the point it stopped).
