RequestLifetimeProvider stored as static reference in ASP.NET MVC

[tillig]

Whenever you new up a RequestLifetimeScopeProvider in the MVC integration, it sets that provider as a static reference with the RequestLifetimeHttpModule:

public RequestLifetimeScopeProvider(ILifetimeScope container)
{
  if (container == null) throw new ArgumentNullException("container");
  _container = container;
  RequestLifetimeHttpModule.SetLifetimeScopeProvider(this);
}

The problem is that if you happen to want to have more than one AutofacDependencyResolver or RequestLifetimeScopeProvider for whatever reason, they effectively become singletons - creating a new one replaces the disposal semantics for the old one.

It might be better to have RequestLifetimeScopeProvider implement IDisposable and update RequestLifetimeHttpModule to allow a queue of providers. During construction, the RequestLifetimeScopeProvider could add itself to the queue; during disposal it would remove itself from the queue.
