 *  Fix: Reverse suppression of connect exceptions. When both a call and its retry fail, we now
    throw the initial exception which is most likely to be actionable.
 *  Fix: Retain interrupted state when throwing `InterruptedIOException`. A single interrupt should
    now be sufficient to break out an in-flight OkHttp call.
