-----------------------------------------
No, but I think the `Socket.close() ` should not be the responsibility of evict
thread.
> tcp status remains in ·CLOSE_WAIT· for a very long time

> Key: HTTPCLIENT-1887
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1887
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 4.5.3
> Reporter: wenqi.huang
>
> run the following code, after the request completed, then wait for some
> seconds, you can use `netstat -an | grep {the server ip}` to see the tcp
> status, the tcp status will transform from `ESTABLISHED` to `CLOSE_WAIT`. and
> it remains in `CLOSE_WAIT` for a very long time, this only happen when the
> server want to close the tcp connection, but the client does not send `FIN`
> to the server.
