> While looking at the code with Amareshwari, we realized that  {{Fetcher#copyFromHost}}
marks connection as successful when {{url.openConnection}} returns. This is wrong. Connection
is done inside implicitly inside {{getInputStream}}; we need to split {{getInputStream}} into
{{connect}} and {{getInputStream}} to handle the connection and read time out strategies correctly.
