beanstalk的使用问题

<?php<br />require_once(realpath(dirname(__FILE__)).'/../pheanstalk/pheanstalk_init.php');<br /><br />class AppRemoteLib {<br />	var $beanhost = false;<br />	var $beanport = false;<br />	var $beanhandle = false;<br />	<br />	function openqueue($host, $port) {<br />		if ($this->beanhost || $this->beanport) return false;<br />		$this->beanhost = $host;<br />		$this->beanport = $port;<br />		$this->beanhandle = new Pheanstalk($host, $port);<br />		if (!$this->beanhandle) return false;<br />		return true;<br />	}<br />	<br />	public function putrequest()<br />	{<br />		try {<br />			$this->beanhandle->useTube('test');<br />			$jobid = $this->beanhandle->put('some data', 1000, 0,1 );<br />		} catch (Exception $e) {<br />			$jobid = false;<br />		}<br />		return $jobid;<br />	}<br /><br />	public function fetch($tube, $timeout=0) {<br />		try {<br />			$this->beanhandle->watch($tube);<br />			$job = $this->beanhandle->reserve($timeout);<br />		} catch (Exception $e) {<br />			return false;<br />		}<br />		if (!$job) return false;<br />		var_dump($job);<br />		sleep(10);<br />		try {<br />			$this->beanhandle->delete($job);<br />		} catch (Exception $e) {<br />			return false;<br />		}<br />		return $job;<br />	}<br />	private function watch($tube) {<br />		$this->beanhandle->watch($tube);<br />	}<br />	private function fetchall($timeout=0) {<br />		try {<br />			$job = $this->beanhandle->reserve($timeout);<br />			if (!$job) return false;<br />			$this->beanhandle->delete($job);<br />		} catch (Exception $e) {<br />		}<br />		return $job;<br />	}<br /><br />}<br /><br />$appremotelib = new AppRemoteLib();<br />$appremotelib->openqueue("192.168.19.128", "11911");<br />$appremotelib->putrequest();<br />$job = $appremotelib->fetch('test', 2);<br />?>

问题是这样，资料上说put命令的tty参数的意思是  --time to run—是一个整形数，表示允许一个worker执行该job的秒数。这个时间将从一个worker 获取一个job开始计算。如果该worker没能在 秒内删除、释放或休眠该job，这个job就会超时，服务端会主动释放该job。最小ttr为1。如果客户端设置了0，服务端会默认将其增加到1。

我设置put的tty的参数为1，$jobid = $this->beanhandle->put('some data', 1000, 0,1 );
并且在fetch函数中获取完成之后$job = $this->beanhandle->reserve($timeout); sleep(10);延迟了10秒才删除job，为什么我的job还是可以删除成功，不是应该这个job会超时吗？

超时就不执行，删除还是删除
