Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @nikomatsakis (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Thanks @glandium! I can only imagine how fun this must have been to find and fix...

Also, nominating for beta as this seems like it's better to get out there sooner rather than later (e.g. 1.11 instead of 1.12)
