The problem is that the TIFF file is all-in-one-strip. Libtiff has support for breaking up uncompressed files into smaller chunks. GDAL has recent support for breaking up 1 bit 1 strip files but general large compressed files like this will choke GDAL.

I will contemplate how to improve the scanline by scanline access to large strips.
