 Replying to [ticket:2171 hamish]:

 specify memory=auto, in which case the value was automatically calculated
 from "tile_height * raster_width * band_count * sizeof_datatype" rounded
 up to the next megabyte or so for good luck.

 internal 40MB for low-resource users who want to import very large files.

 As a side note: wouldn't a memory parameter also be beneficial for
 r.out.gdal ?
