Hi, The test interrupts the thread, which will close the database file (as always with FileChannel). Subsequent close calls will fail, this is a bug that I need to fix. However, I don't think this will corrupt the database file.
Interrupting the thread is one way to test it, killing the process is another. There are already such tests, and so far I couldn't reproduce the problem. Additional tests are with a file system implementation that simulates re-ordering writes, and power failure. Simulating power failures I have, but re-ordering writes is still missing. Then, real power failure tests are needed. This will require some work, but I think it is important. I will work on that.
