> In a Linked Data environment servers have to fetch data off the web. The speed at which such data 
> is served can be very slow. So one wants to avoid using up one thread for each connections (1 thread = 
> 0.5 to 1MB approximately). This is why Java NIO was developed and why servers such as Netty
> are so popular, why http client libraries such as https://github.com/sonatype/async-http-client are more
> and more numerous, and why framewks such as http://akka.io/ which support relatively lightweight
> actors (500 bytes per actor) are growing more viisible.
> Unless I am mistaken the only way to parse some content is using methods that use an 
> InputStream such as this:
>     val m = ModelFactory.createDefaultModel()
>      m.getReader(lang.jenaLang).read(m, in, base.toString)
> That read call blocks. Would it be possible to have an API which allows
> one to parse a document in chunks as they arrive from the input?
