Apropos earlier threads, Miguel de Icaza has an interesting blog post on 
callbacks and C#Async:

He writes:

I agree with him on this, despite JavaScript closures. If anything, closures 
can potentially exacerbate the memory accounting problem.

I think he is also right in quoting Dijkstra (I reproduce part of the quote 
below):

Lest I be perceived as “complaining”, I bring this up as academically 
interesting, not as a bumptious attempt to influence the future of NodeJS :-).
