Differentiate synchronous and asynchronous error of an AIO operation

[Zhong Yu]

Thanks Alan, I think I have a  better understanding of fixed thread
pool configuration. If a handler is potentially blocking, it has to
dispatch the real work to another thread, but that's not hard. Under
this configuration it's easy to add flexible threading strategies.

I still don't have a clear understanding of the official behavior of a
group with user-supplied executor. Reading the implementation doesn't
help - it got me more confused. Well I'll steer clear from them. And
the default group too.

Any reason there can't be a fixed internal thread for these I/O requests?
