Resetting Config to Default .ini Values at Runtime

I’ve been working with the GConfig object and config files for some time now. The issue I’m having now is trying to revert back to defaults (blank my input.ini and revert to defaultinput.ini, for example). I can easily enough do it by blanking the input.ini and restarting the game, but I can’t seem to get a reinitialization to happen while the game is running. Do I need to reinitialize inputsettings somehow? None of the code is very clear on how that happens or how I can force a reload after I clear input.ini to pick up defaultinput.ini settings.
