Watches don't get set/fired if you call getChildren an a non-existent node (i 
think that was the question). See:

http://grepcode.com/file/repo1.maven.org/maven2/org.apache.zookeeper/zookeeper/3.4.3/org/apache/zookeeper/server/FinalRequestProcessor.java?av=f#326

NoNodeException is thrown before the call to ZKDatabase#getChildren where the 
watches are set.
