/**
* Refreshes in-memory configuration and state information.
*
* Useful after a page request is made that changes configuration or state in
* a different thread.
*
* In other words calling a settings page with $this->submitForm() with a
* changed value would update configuration to reflect that change, but in the
* thread that made the call (thread running the test) the changed values
* would not be picked up.
*
* This method clears the cache and loads a fresh copy.
