> libhdfs++: Catch exceptions thrown by runtime hooks

> Right now there's nothing to stop a user supplied event callback from
> throwing and unwinding the stack on the asio worker thread. This can lead to
> async filesystem operations that never complete because the stack was unwound
> before setting up the next async io call.
> Best practice is to be really careful about what is done inside event hooks
> and callbacks: don't throw, sleep, or anything else that might block. I've
> seen a few issues pop up because a hook was made for monitoring purposes and
> later on stuff that was able to throw was added without realizing where the
> exception may end up.
