Looking at readGDAL, it seems that GDAL.close is called on the open file 
handle before the data are returned. This should give you the handle ... 
destroyed ... messages for each file you open.

In the C code of package rgdal, I see reference to GDALOpen(), but not 
to GDALClose(). I guess it should?
