Ray Strode bed3bb45f7 background: don't load the same image more than once concurrently
If a background gets requested from the cache while it's still
being loaded from an earlier call, then there will be two concurrent
loads of the same file.

That concurrency is mitigates the effectiveness of the cache and
also causes leaks.

This commit consolidates file loads so that concurrency doesn't
happen.
