Oliver, There have been an effort to provide such kind of options in GDAL RFC 24 ( http://trac.osgeo.org/gdal/wiki/rfc24_progressive_data_support) for the drivers involved in slow IO operations an possibly in use of multiple threads in this regards. I guess it might be a bit unrelated to this issue but just in case.
