Note that catching the exception means allowing the exception to interrupt
wherever in your loop execution may be, so you can not expect such a loop exit
to give you a final complete loop execution. See suggestions (mine and
others) for using signal handlers to accomplish orderly loop termination
based on modifying a while loop condition from a signal handler (which
returns to continue execution of the loop where interrupted).
