4letter word (monitor) issue in 3.3.0 with nc (netcat)

[Patrick Hunt <ph...@apache.org>]

I discovered a problem using nc with 3.3.0 such as:

echo stat | nc localhost 2181

full details here: http://bit.ly/ahkHdb

The failure is intermittent for me (timing issue) but I wanted to let 
everyone know about it given that nc is frequently used for monitoring. 
Given the nature of the problem you may be seeing results inconsistent 
with the status of the server (server up but stat not returning data).

This does not effect the functioning of the server, just the command 
itself is impaired.

We'll probably do a 3.3.1 relatively soon to correct this (and a few 
other issues that are slated for 3.3.1).
