4756. [bug] Interrupting dig could lead to an INSIST failure after certain errors were encountered while querying a host whose name resolved to more than one address. Change 4537 increased the odds of triggering this issue by causing dig to hang indefinitely when certain error paths were evaluated. dig now also retries TCP queries (once) if the server gracefully closes the connection before sending a response. [RT #42832, #45159]
