Requests an asynchronous close of the stream, releasing resources
related to it. When the operation is finished callback will be
called. You can then call OutputStream.closeFinish to get
the result of the operation.
The asynchronous methods have a default fallback that uses threads
to implement asynchronicity, so they are optional for inheriting
classes. However, if you override one you must override all.
