Exactly.  Libtiff holds the data for a single strip in memory, so putting the
whole image into one strip is just not reasonable in the general case.

The 1M-default for MaxStripSize was chosen because some fax software cannot
read Multi-Strip TIFF files:  Since *most* fax pages fall under the 1M limit,
the whole image ends up in one strip for those cases (just as it did for gs <
8.71).

Lee, do you have a specific problem with such faulty fax software?  Only then
would I recommend -dMaxStripSize=0.
