I remember this from last year. It seemed to me at the time (and now) 
a sort of std::async for iostreams implementation that pushed the 
formatting labour onto worker threads. If I am wrong on this, do say.

As much as this might be worthy, what I had in mind was an iostreams 
that doesn't mind out of order data readiness, so if I schedule a 
gather read from offsets A, B, C and D in a file, and they complete 
in the order D, B, C, A with lumpy periods of time between 
completions, the iostreams framework gets on with processing instead 
of waiting around for all to complete.

Such an iostreams framework may seem excessively complex, but it's 
latency optimal.
