pings, but it did not track whether the reply pongs were received. With this
    update OkHttp requires that every ping receive a response: if it does not
    the connection will be closed and the listener's `onFailure()` method will
    be called.

    Web sockets have always been had pings, but pings on HTTP/2 connections is
    new in this release. Pings are used for connections that are busy carrying

 * This is because those two hosts share the same IP address. This is an old, bad design decision
 * that makes `java.net.URL` unusable for many things. It shouldn't be used as a [Map] key or in a
 * [Set]. Doing so is both inefficient because equality may require a DNS lookup, and incorrect
 * because unequal URLs may be equal because of how they are hosted.

//
// Design decisions made:
// * Backing store for tensor memory has an associated deallocation
//   function.  This deallocation function will point to client code
//   for tensors populated by the client.  So the client can do things
//   like shadowing a numpy array.
// * We do not provide TF_OK since it is not strictly necessary and we
//   are not optimizing for convenience.
// * We make assumption that one session has one graph.  This should be

		if _, err = er.HealObject(ctx, bucket, object, "", madmin.HealOpts{NoLock: true}); err != nil {
			return err
		}
		// Fetch FileInfo again. HealObject migrates object the latest
		// format. Among other things this changes fi.DataDir and
		// possibly fi.Data (if data is inlined).
		fi, metaArr, onlineDisks, err = er.getObjectFileInfo(ctx, bucket, object, opts, true)
		if err != nil {
			return toObjectErr(err, bucket, object)

     * The default value of 0 disables client-initiated pings.
