Steven Wong updated ZOOKEEPER-553:
----------------------------------

    Description: 
Using zkpython with ZK 3.2.1 release:

  import zookeeper as z
  zh = z.init(...)
  z.state(zh)  # returns 3 == z.CONNECTED_STATE
  # kill standalone ZK server
  z.state(zh)  # returns 0 == ???

The problem is that 0 is not a state defined by the C client's zookeeper.[ch]. 
Perhaps 0 should've been defined as something like DISCONNECTED_STATE? (Java's 
KeeperState.Disconnected is 0, if that matters.)

If the fix is to define 0 as a new state, changes will be needed to both the C 
client and zkpython. Not sure about other bindings.
