* Switch sharing kwarg default to False Resolves #1705 * Replace GDALOpenShared with GDALOpen except in one shim * Revert two open_dataset to GDALOpen * Run tests under gdb * Increment ref count in WarpedVRTBase * Open a new dataset handle in WarpedVRT * Remove gdb * Remove exceptions from open_dataset in _shim1 Makes usage much easier * Fix in-memory dataset leaks in _reproject
