Thin seems like an interesting server, but if you look at the issue tracker, it has not been maintained for many years. The recent changes to the thin handler have caused issues (#1583).

I don't think we should be maintaining handlers for servers in rack. They should provide their own adapters. If the maintainer of thin is not wiling to do this, should we be on the hook for trying to maintain it within rack? Including version checks?

Here is what I think I'd willing to do.

1/ I want to remove the thin handler.

2/ I want to move that code to the thin repository.

3/ I want a new release of thin with this code.

@macournoyer what do you think? What should we do?
