Subject: [PATCH] single-conn mode: Kill the cached idle connection. BZ 853432

The multi-downloader manages connections as necessary, caching
at most one downloader per host. But there's one more connection,
used by the legacy downloader.  In case keepalive=1 (default),
it's still connected, possibly to the same connection-limited
host.  Kill it.
