I've seen both words used for the third initial. I *believe* the
first time this term was coined the word IS was used, but frankly, IN
makes more sense to me.

Classes whose sole purpose is to add RAII to a concept are often
referred to as "RAII harnesses". Whether the term "harness" is
generally accepted in the C++ vernaculor, I'm not sure, but "RAII
harness" has been used often enough I thought anyone familiar with
RAII would know what was meant. Granted, I really meant RAII in
general, so I should have been more careful in my wording. Sorry for
any confusion.
