Issue #4237 has been updated by Hiroshi NAKAMURA.


Here's a link to OpenSSL doc Aaron said: http://www.openssl.org/docs/ssl/SSL_shutdown.html

You should read it directly, since it's not simple as "SSL_shutdown should be called until it returns 0". We should handle -1 as well, if we want to ensure bi-directional SSL close. Plus we should check OpenSSL versions behavior.
