I agree that the patch is likely not in FWTools because FWTools uses
a stock external libjpeg instead of the adjusted GDAL libjpeg.

I'm not exactly clear what the temp file is for.  I have the vague
impression it is only needed with progressive jpegs, but I could be wrong.

I don't know for sure where it is created.
