/**
 * Return a stream for reading from stdin.
 * 
 * This function returns a stream which provides data read from stdin,
 * and a future to signal read results.
 * 
 * If the stream's readable end is dropped the future will resolve to success.
 * 
 * If the stream's writable end is dropped the future will either resolve to
 * success if stdin was closed by the writer or to an error-code if reading
 * failed for some other reason.
 * 
 * Multiple streams may be active at the same time. The behavior of concurrent
 * reads is implementation-specific.
