+ * daemonize - turn this process into a daemon.
+ *
+ * This routine forks us off to become a daemon.  It returns false on failure
+ * (ie. fork() failed) and sets errno.
+ *
+ * Side effects for programmers to be aware of:
+ *  - PID changes (our parent exits, we become child of init)
+ *  - stdin, stdout and stderr file descriptors are closed
+ *  - Current working directory changes to /
+ *  - Umask is set to 0.
