So the story is that SslConnection used to dispatch reads, so there
was no need to dispatch again in HttpClient.
However, SslConnection has been optimized to not dispatch anymore, but
the HttpClient code was not changed.
I'll restore the default to not call setDispatchIO(false) when using SSL.

In any case, there is no problem. HttpClient is completely
asynchronous, so it will never block.
The usual contract - and I will clarify this in the documentation - is
that if you need to do "heavy" code in the callbacks you need to
dispatch yourself.
HttpClient cannot dispatch callbacks for you because in the normal
case it will be a performance hit.

Thanks for the heads up.
