The *interface* is extremely simple, but I have as a principle not to put
something on my web site unless I have some html file with it to explain
what it is about. The *implementation* certainly incurs some overhead (well,
it's a trade-off between efficiency and portability).

Oh, certainly, and especially for the implementation of finalization - I
guess. I just mentionned there was a portable solution. I did not mean it
was the best solution in every situation, but certainly in the case where
you want portable software components.
