-Description from the upstream commit:
-
-  OpenSSL 1.0.2f changed the behavior of SSL shutdown in case the TLS connection
-  was not fully established (commit: f73c737c7ac908c5d6407c419769123392a3b0a9).
-  This somehow resulted in Net::SSLeay::shutdown returning 0 (i.e. keep trying)
-  which caused an endless loop. It will now ignore this result in case the TLS
-  connection was not yet established and consider the TLS connection closed
-  instead.
