OK, one thing I guess I did not understand was that the Jenkins webapp
does not need to be running on the slave. In fact, shutting it down
solved my problem. I was then able to start the slave by doing

java -Djava.awt.headless=true -jar slave.jar -jnlpUrl
http://master:8080/computer/slave/slave-agent.jnlp -secret
<secret-key>

And in fact I could start this command with 'nohup' and pipe its
output to a file (and put & on the end of it) and I don't need to be
logged in on the slave for my builds to work. I'll set up this command
to be run automatically at boot time and then everything will 'just
work' if the machine is rebooted.

Thanks very much for your help.
