I think FlushCache() is needed only when you write to disk, which is of course not the case for 
a MEM dataset. BTW, I have ran into probs with MEM and GDAL Python (should we call it pyGDAL?): 
in OpenEV, removing a MEM layer does not free its memory... have you observed this in C? Or it 
may be OpenEV related only...
