I'm well aware of interfaces. In fact my initial version used an
interface for this. However, there are other aspects of the equation
that has to be taken into account to. For instance, using a base class
means you can inherit functionallity from the baseclass. This makes it
much easier to implement things, because we can do the fallback async
wrapper in the base class, and it makes it much easier to do wrapping of
streams.

In fact, if you look at Java and .Net you will see that their streams
are objects too, not interfaces.
