Subject: [PATCH 1/2] preventing hang when io readable, but no app-data

TCPSocket may be readable due to handshake data arriving (NewSessionTicket's may arrive unprompted) - this essentially calls a SSL_read to process handshake data and returns nil when an actual EOFError has been raised, otherwise just returns (probably the symbol :wait_readable)
