Detect hung/unresponsive nagios server

[GoogleCodeExporter]

What steps will reproduce the problem?

1. no problem reported on the Nagios server - green "No problem"
2. Nagios server is developing a problem with following characteristics:
  * pingable
  * http port still responding but never returning any data

Basically a server that is still alive but has developed a disk problem and
all processes are just hanging, waiting for disk I/O.

What is the expected output? What do you see instead?

I would expect that Nagios checker is reporting that it can not get any
data back from the server (Maybe a "orange" state - see issue 59). Instead
I see green "No problem".

What version of the product are you using (Nagios Checker and Nagios)? On
what operating system?

Nagios Checker 0.11.1
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b4pre) Gecko/2008021104
Minefield/3.0b4pre

An easy way to test the code:  write a server-side script that just takes 
forever to
respond and point nagioschecker at it.  Something like:

<?php sleep(600); ?>
