I think the clean-up can be done in the end-proc (see #1004).

Thanks, I had left the backends code alone because I had no idea how you're even supposed to wrap that kind of thing, and I guess the answer is you just don't.

A new release after this is merged would be very appreciated for Ruby HEAD compatibility

I'd like to second this request, because it seems rugged cannot be used as a git gem in the meantime :/

nevermind, it seems like I had a corrupted cache. A first attempt a gem 'rugged', github: 'libgit2/rugged' created vendor/libgit2/build, which then broke the later attempt using gem 'rugged', github: 'libgit2/rugged', submodules: true, so I'm unblocked for now.

A release definitely would be nice though.

+1 for @nobu's PR and a patch release :)
