What about generalizing that API a bit, and rolling it up to 
SelectableChannel with methods like:

   public abstract void await(int ops);
   public abstract void await(int ops, long time, TimeUnit unit);

...where ops must conform to validOps().

This way it becomes trivial for anyone to mix blocking and non-blocking 
APIs which is definitely a common API usage.
