First thanks for this great work and its really an honor to me that
such great coders like you answer my questions.

The main reason I asked the original question is not that much about
raw performance but more about code-simplicity in the sense to code
like in a traditional blocking style but still have better performance
and less blocking (not necessarily none).

So I hoped to get a somehow sulution with my original attempt.

Regarding CountedCompleter an example usage for IO would certainly
help me, because I don't know where I should plugin the
completion-callback for async-IO or alternatively do the blocking IO.
