Catching Memcache Exception...

It doesn't seem like one can catch Memcache exception

    PHP Fatal error:  Uncaught exception 'Phalcon\Cache\Exception' with message 'Cannot connect to Memcached server' in phalcon/cache/backend/memcache.zep:113

This is what I am currently doing:

    $frontCache = new Data(array(
        'lifetime' => 0
    ));

    try {
        $service = new Memcache($frontCache, array(
            'host'       => $host,
            'port'       => $port,
            'persistent' => $persistent
        ));
    } 
    catch (\Exception $e)   // also tried with \Phalcon\Cache\Exception
    {

    }

    return $service;

There should be a way for phalcon/cache/backend/memcache.zep to pass on the exception back to caller so it can be handled in userland.

OR am I simply not catching it correctly?
