MINOR: stream-int: automatically mark applets as ready if they block on the channel

If an applet reports being blocked due to any of the channel-side flags,
it's reportedly ready to deliver incoming data. It's better to do this
after the return from the applet handler so that applet developers don't
have to worry about details related to flags ordering.
