No, when a user logs out all processes that are children to that shell instance 
are sent a HUP signal (Hang UP). A process may choose to ignore that signal. 
Every well written daemon and server process SHOULD do that (among other things).

I use " start" instead of " run" and so should Nancy. The 
problem is in Tomcat getting HUP signal, but in loosing a console, I think.

Or for instance, I connect to my company, locate a file for download, place it 
in script, run the script with nohup and disconnect. The download will go on.
