That appears to be a problem with the standard php curl bindings. It
doesn't happen with pecl_http (https://pecl.php.net/package/pecl_http)

    declare(ticks=1);

   $shutdownHandler = function () {
       echo 'Exiting';
       exit();
   };

   pcntl_signal(SIGINT, $shutdownHandler);

   while (true) {
       $client = new http\Client();
       $client->enqueue(new http\Client\Request("GET",
"http://blackhole.webpagetest.org"));
       try {
           $client->send();
       } catch (Exception $e) {
           print("\n".$e->getMessage()."\n");
       }
   }
