loop to check if ros is running / maybe install a handler. it lags every time you send ROS a sigterm through ctrl-c at the prompt

this will probably let us flush the buffers for the log file and close it before we exit, for example, so that if we get SIGTERMed we don't lose information that might help us understand why.
