写了一个wordpress目录检测的脚本，但是有时候会出现死循环不知道是什么原因

[面包加火腿]

代码入下，求大牛帮看一下

def LoadPlugin(self):
		print "\33[33mStart Plugin scan,please wait...\33[0m"
		self.count = 0;
		PluginThread=[]
		ExistList = []
		self.PluginQueue = Queue(maxsize = 10000)
		linecount = len(open('./loopholes_plugin.txt','rU').readlines())
		Plugin_Path =  "http://{0}".format(self.url)
		if(os.path.exists(r'./loopholes_plugin.txt')):
			file = open(r'./loopholes_plugin.txt','r')
			for line in file:
				PluginList = line.strip()
				self.PluginQueue.put(PluginList)
			file.close()
			self.PluginQueue.cancel_join_thread() 
		else:
			print " file does not exist!"
		start = time.time()
		for count in range(5):
			t = threading.Thread(target = self.PluginScan,args = (linecount,ExistList))
			t.setDaemon(True)
			t.start()
			PluginThread.append(t)
		for i in PluginThread:
			i.join()
		print ""
		for j in ExistList:
			print "\33[31m%s\33[0m" %j
		end = time.time()
		#print "Plugin_Scan_Time: %f s" % (end - start)

	def PluginScan(self,linecount,ExistList):
		thread = threading.current_thread()
		while 1:
			Plugin_Path =  self.url
			if(not self.PluginQueue.empty()):
				PluginDir = self.PluginQueue.get()
			else:
				break
			Plugin_Path = "%s/wp-content/plugins/%s/" %(Plugin_Path,PluginDir)
			try:
				Plugin_re = requests.get(Plugin_Path,headers = HEADERS)
				if(Plugin_re.status_code == 200 or Plugin_re.status_code == 403):
					ExistList.append(PluginDir)
				Plugin_Path =  self.url
			except:
				print "\33[31mconnect fail\33[0m" 
				break
			self.count+=1
			sys.stdout.write('Current full schedule:'+str(str(self.count)+'/'+str(linecount))+"\r")
			sys.stdout.flush()

会有县城不退出，有时候就会一直死循环。
