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
code.
