-----------------------------------------------------------

The {{src/test/utils.cpp:64}} helper that failed is:
{code}
JSON::Object Metrics()
{
  UPID upid("metrics", process::address());

  /* For some reason, this call times out and never completes. */
  Future<http::Response> response = http::get(upid, "snapshot");

  AWAIT_EXPECT_RESPONSE_STATUS_EQ(http::OK().status, response);
  AWAIT_EXPECT_RESPONSE_HEADER_EQ(APPLICATION_JSON, "Content-Type", response);

  /* The `response->body` below is basically an unguarded `Future::get` 
    because the two AWAIT calls above are the EXPECT variety, meaning 
    that they do not return from the function when they fail. */
  Try<JSON::Object> parse = JSON::parse<JSON::Object>(response->body);
  CHECK_SOME(parse);

  return parse.get();
}
{code}
