"Fastest wins" parallel download with Hopac
One of the main features of Hopac - selective synchronization using "alternatives". In this snippet we download three web pages in parallel and the one that finishes first "wins" (or the timeout alternative becomes available for picking). What's nice in this solution is that the other two downloading jobs are cancelled immediately when the winner/timeout is available (i.e. an implicitly provided to the Asyncs CancellationTokens are cancelled). Alts is highly composable and, for example, the whole Alt.choose [ ... ] thing could be nested in another Alt.choose or combined with <|> or <&> operators with another Alt and so on.
