> In {{ThreadPoolRequestReplicator.NodeHttpRequest.run()}} the main logic is in
> a {{try}} block, during which all {{Exceptions}} are caught and handled
> properly. However we need to call an {{Object.notify()}} after that so it's
> crucial that the error handling covers every scenario.
> Because of this we should catch all {{Throwables}} (instead of only
> {{Exceptions}}), otherwise - should we encounter an {{Error}} for example -
> we might end up in a _deadlock_ state.
