This broke on Windows: https://github.com/simonw/sqlite-utils/runs/5056912641

            if recreate and os.path.exists(filename_or_conn):
>               os.remove(filename_or_conn)
E               PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\runneradmin\\AppData\\Local\\Temp\\pytest-of-runneradmin\\pytest-0\\test_recreate_False_True_0\\data.db'

I'm going to revert it from main for the moment.
