In my opinion there is a little too much veneration of "tight" circuits. The justification for a tight circuit is allegedly to allow a glide approach to the runway in the event of engine failure in the circuit. The reality is that one is no more likely to suffer engine failure in the circuit than anywhere else, and yet we do not afford ouselves the luxury of a runway constantly nearby when travelling from A to B. For those of us flying turbo charged aircraft (especially) the risk of engine failure due to shock cooling caused by full power climbs followed by power off glides , greatly increases the risk of engine failure. There is no point in taking precautionary action against engine failure, if in doing so one is encouraging it!
