If you are writing something that is supposed to be a long-running 
server process you should explicitly ignore all the signals that you 
don't want to kill it, and have handlers for anything that might be 
useful.  For example SIGHUP is often used to tell a program to re-read 
its configuration file.  Since the source code for the whole system is 
available you should be able to find examples.  Or look at the *bsd 
versions if you are concerned about accidentally duplicating some GPL'd
