Well, the idea is to detach the running SAGE instance from the shell
to let it run in the background until it is killed or the system is
rebooted.
There is more than one way to do it: For a good C example see
http://www.enderunix.org/docs/eng/daemon.php - for a python example
see http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/66012
The python example could be more or less copied (I guess because I am
not a python expert), but it should be done very early in the SAGE
startup as far as I can tell. Writing a little C wrapper that just
does
i=fork();
if (i<0) exit(1); /* fork error */
if (i>0) exit(0); /* parent exits */
/* child (daemon) continues */
execv("./sage");
might be easier.
