And that's exactly where I'm headed. I've created API that seems to be
usable and meat mine and others requirements (not that I'm not saying it
cannot be improved -- I'm always happy to hear comments) and now I'm
starting to concentrate on the reusing of the grabbed memory. At first
I wasn't sure how this can be managed but thanks to many comments
(including yours, thanks!) I have an idea of how the thing should work
and what I should do from now.
