// on it. Must be deleted after all V8 objects created using its isolate. It
// facilitates creating objects from JSON and running scripts in isolated
// contexts.
//
// Currently, multiple AuctionV8Helpers can be in use at once, each will have
// its own V8 isolate.  All AuctionV8Helpers are assumed to be created on the
// same thread (V8 startup is done only once per process, and not behind a
// lock).  After creation, all public operations on the helper must be done on
// the thread represented by the `v8_runner` argument to Create(). It's the
// caller's responsibility to ensure that all other methods are used from the v8
// runner.
