// completion callback helper
// A helper class for completion callbacks, designed to make it easy to run
// tests involving asynchronous operations. Just call WaitForResult to wait
// for the asynchronous operation to complete.
//
// NOTE: Since this runs a message loop to wait for the completion callback,
// there could be other side-effects resulting from WaitForResult. For this
// reason, this class is probably not ideal for a general application.
//
// Base class overridden by custom implementations of TestCompletionCallback.
