That's part of TLS v1.1. There is currently an experimental implementation of
TLS v1.1 in HEAD which will be backported to 1.0.1 at some point.

Other versions of OpenSSL using TLS 1.0 or earlier can work around the CBC
issue by sending empty fragments though some implementations are known to have
problems with them.
