Mario, 

And it *should* work but there are some issues with how I bound GDAL and
OGR in Python that in retrospect are perhaps subideal.   Just today Howard 
Butler has browbeat me into improve management of OGR features and 
geometries on the OGR side of the house.

Well, really the only way to be sure it is closed to to ensure there are
no remaining references to the dataset.  The effectiveness of the
FlushCache() method varies by driver.  Generally speaking it forces image
data out of the raster cache into the driver to be written to disk.  Some
drivers also write any pending header information so the file is in
a consistent state on disk, but not all.
