Added an 'Are there testbed-specific daemons that could interfere with my

experiment?' entry, after getting some questions about this.

<h3>Are there testbed-specific daemons that could interfere with my
experiment?</h3>
<p>
The only daemon that the testbed adds to the OS's standard set is
<code>healthd</code>. This daemon periodically polls things such as
motherboard/CPU temperature and fan speed, and reports them back to
our <code>boss</code> node. We have picked a large polling interval
(five minutes) to minimize the impact on nodes. If you are worried
about side effects, however, you can safely kill it off.
<code>healthd</code> is stared by <code>/etc/testbed/rc.healthd</code> .
</p>
<p>
If you have requested automatic routing on your nodes with the
<code>tb-set-ip-routing</code> command in your NS file, this will
start <code>gated</code> on all of your nodes.
</p>
<p>
We have left all daemons started by the operating systems' default
configurations (such as <code>cron</code>) enabled, so you should also
look at them if you are concered about running processes affecting
your experiment.
