Cant check the connection state before executing

[KnightE]

It seems that the only way of getting the connection state, is executing the executor, and checking the reply of batch.
If the redis node goes down, executor will return the result in $timeout ms.
It should not wait the time, and this issue could make big problem in product environment.
Is there any good suggestion? Or did I miss something important?

$libredis = Libredis();
$connection = $libredis->get_connection('127.0.0.1:6379');
$batch = $libredis->create_batch();
$executor = $libredis->create_executor();
$batch->cmd('set', 'foo', 'bar');
$executor->add($connection, $batch);
$executor->execute(1000); // I will wait here for 1000 ms if the connection is broken

I use fsockopen to check the connection before executing.
It's better that libredis could solve it.
