Are you ignoring SIGHUP?  If you are, then change it so that the default
action is taken (SIG_DFL), which is to croak the process.  If you don't
wan't the process to cleanup first, then trap the SIGHUP signal, and
die gracefully.  If you want the process to die of it's own accord sometime
later, then trap SIGHUP to do a setpgrp() and freopen() stdin, stdout,
and stderr (this will disassociate it from your terminal).

Hope this helps.
