Patrick Hunt updated ZOOKEEPER-117:

    Status: Open  (was: Patch Available)

There is a potential race condition with this code:

1) say leader shutdown is called
2) shutdown will call cnxAcceptor.halt()
3) acceptor is currently blocked on accept (for up to 1 sec)
4) shutdown method completes, including shutting down entire followers set 
5) accept call in acceptor returns true (socket != null)
6) acceptor now adds followerhandler to followers set
