+      body: >
+        This prevents an image download error loop where the delta image on the
+        delta server is present,
+
+        but some aspect of the delta image or the base image on the device does
+        not match up, causing
+
+        the delta to fail to be applied to the base image.
+
+
+        Delta apply errors don't raise status codes as they are thrown from the
+        Engine (although they should),
+
+        so if an error with a status code is raised during this time, throw an
+        error to the handler
+
+        indicating that the delta should be retried until success. Errors with
+        status codes raised during
+
+        this time are largely network related, so falling back to a regular pull
+        won't improve anything.
+
+
+        Upon delta apply errors exceeding DELTA_APPLY_RETRY_COUNT, revert to a
+        regular pull.

+        delta image,
+
+        this means the server is not able to supply the resource, so fall back
