Stop WordPress from reserving slugs for media items?

I am experiencing some odd behavior, that apparently happens "out of the box" with WordPress.

If I upload a file through the media manager called: services.jpg; then go try to create a page with the permalink http://ift.tt/1EpeD4A; The slug services-2 is given instead, because the attachment is already using that slug.

Visiting http://ift.tt/1EpeD4A loads the attachment page.

I have not enabled any plugins or added anything into functions.php to modify the rewrites for attachments.

Has anyone run into this before? Know where to start to disable this functionality?
