+        Previously, we'd time-out a pull operation after unsuccessfully retrying
+        for about 17 minutes (for details see commit
+        582487f832c59c2f734a780ab0492833f29002c9). This worked fine in most
+        situations, but we have seen at least one case of a particularly
+        unreliable network connection that would not be able to finish a large
+        pull when operating under this policy.
+
+        This commit:
+
+        * Completely removes timeouts from image pulls. We'll keep retrying
+          forever, or until users cancel the pull. (From the perspective of the
+          REST API, "canceling" mean closing the HTTP connection. This is what
+          happens when a user Ctrl+C during a pull in the CLI, or, say, we kill
+          a curl process that was using the REST API to pull image.)
+        * Still uses exponential back-off, but we now limit the interval between
+          retries to 5 minutes. The rationale is that some very unreliable
+          networks may be up only for relatively small time windows. Therefore,
+          using intervals that are too long would increase the risk of missing
+          these windows.
+        * Tries to avoid flooding the log stream with messages about retries.
+          We'll log every retry attempt up to the 10th. After that, we'll log
+          retries only once about every 2h. This retry count is reset every time
+          we successfully download any amount of data.
