Such an simulation does hardly cover all possible problems. In general there was an statement about old interbase database which should be "up again" shortly after an power fail in an tank-environment caused by firing the gun. There is some chance that firebird can recover after crash. The Problem itself does arise from the order the physical writes are done. If the OS (or even the disk) does reorder writes I would suspect to generate problems. You can simulate power-fail by using QEMU emulation and killing the emulator.
