Description

A new ZooKeeper client will start three threads, the SendThread, EventThread and LoginThread. I belive that these threads will be shutdown after call the zk.close. I test that the SendThread and EventThread will be die, but LoginThread is still alive. The stack is:

"Thread-0" daemon prio=10 tid=0x00007ffcf0020000 nid=0x69c8 waiting on condition [0x00007ffd3cc25000]
java.lang.Thread.State: TIMED_WAITING (sleeping)
at java.lang.Thread.sleep(Native Method)
at org.apache.zookeeper.Login$1.run(Login.java:183)
