This should address issue #9, with the caveat that I'm very new to and bad at Rust. It seems to work for me though!

Thanks for the thorough review!

I'll admit my PR was after a few frustrated hours learning more about lifetimes and Rc/Arc. I was excited when I got something that worked and made sense to me. I did try at some point to wrap the raw pointer, but I was having so much other trouble that I undid it and then forgot about it.

Anyway, the changes you requested turned out to be surprisingly easy and work fine in my quite limited testing.

Also, sorry for the force-push. I was untidy with my branching, and needed to move another commit off master to keep this PR clean. I'll do better with branching for PRs next time...
