Audit log in HC 5
We have a report of the async client stopping due to some sort of IOReactor
crash. This is the same class of problem we saw in HttpAsyncClient in the
4.x days, and which was supposedly fixed in the new version. Can we add
diagnostics for this issue?

Now I remember why we never used this. It appears that there is no way to
customize the callback via `HttpAsyncClientBuilder`.

Oh right, this slipped my mind. I'll continue investigating.

There is now a simple callback that just logs exceptions by default.
One can provide a more complex implementation that, for example,
maintains a buffer of the most recent exceptions like the audit log in
4.x

Hope this helps

I'm currently focused on the connection pool issue, so I'll have to deal
with this later. But I was wondering why the 5.x line no longer features
the IOReactor audit log.

Is there a log of the session exhibiting the problem? What kind of
additional diagnostics do you have in mind?
