	// FIXME: this fails sometimes on macOS, the file being 88 bytes
	// (1 entry) smaller than we expect it to be.
	debug_assert_eq!(self.file.metadata().unwrap().len(), self.length);

Sometimes (on macOS) it fails when adding multiple blobs, even though everything seems to work correctly and all tests pass. Just above those lines we write a new a entry and sync that to disk, but we get a difference in the "actual" file length and the file length in-memory (self.length).
