Description

The accept loop in OpenSSLSocketImpl in the case of support_downgrade enabled will wait for incoming bytes on the accepted socket before allowing another socket to be accepted. This will lead to significant throughput issues for accepting new connections (e.g. during a master failover), or may block entirely if a client doesn't send any data for whatever reason.

Marking as a bug due to the potential for blocking incoming connections.
