The "Apply" button in the main window calls stopBarrier() immediately
followed by startBarrier(). The startBarrier() function reloads the
configuration. The fact that the "Apply" button applies configuration
changes is incidental; the "Start" button also applies new settings.
"Reload" more accurately describes the function that the button
performs.
