By the way, since libtiff uses memory mapped files as default,
using multiple handles isn't that bad, because the handles will all
access the same memory mapping, at least on unices.

On windows, this is turned off. Perhaps it would be a good idea to enable
sharing
on windows. It just involves generating a unique string without back
slashes, for
each file name.
