+Do not setup SIGHUP signal handler if we are in the batch mode
+
+Top enables a signal handler for the SIGHUP signal (loss of terminal).  While
+this makes sense for top's default interactive mode, it doesn't make any sense
+for batch mode. If you run top in nohup just to collect data over time and
+disconnect top finishes which is not what one would expect.
