Thanks for posting this.  It was an incredibly useful read for 
me!  Given that the code I write is generally compute-intensive, 
not I/O intensive, I'd never given much thought to the value of 
futures in I/O intensive code before this discussion.  I stand by 
what I said before:  Someone (not me because I'm not intimately 
familiar with the use cases; you might be qualified) should write 
a std.future module for Phobos that properly models the 
**abstraction** of a future.  It's only tangentially relevant to 
std.parallelism's charter, which includes both a special case of 
futures that's useful to SMP parallelism and other parallel 
computing constructs.  Then, we should define an adapter that 
allows std.parallelism Tasks to be modeled more abstractly as 
futures when necessary, once we've nailed down what the future 
**abstraction** should look like.
