 // The FileSystem APIs are all asynchronous; this testing class wraps up the
 // boilerplate code necessary to deal with waiting for responses. In a nutshell,
 // any async call whose response we want to test ought to be followed by a call
 // to BlockUntilNotified(), which will (shockingly!) block until Notify() is
 // called. For this to work, you'll need to ensure that each async call is
 // implemented as a class method that that calls Notify() at an appropriate
 // point.
