+Sending this process SIGHUP will (eventually) result in a message;
+
+SIGQUIT (^\) will result in a message immediately.
+
+SIGINT (^C) will result in an error trace immediately.  This is the result of the -async option on signal handlers
+
+Signal 21 (URG) will pop the dialog up!
+
+Pressing the "Long Job" button will perform a single, long calculation where no buttons presses will have immediate effect, but SIGINT will interrupt the calculation prematurely
