Overview
Comment:Work around an AFP file system byte-range locking error caused by opening and closing a second file descriptor on the database file as RDWR which clears the exclusive byte-range lock and results in an fcntl error when the AFP locking code attempts to clear it afterwards. This error is caused by the test harness and isn't a flaw in the sqlite or its implementation of AFP file locking. (CVS 4172)
