WARNINGS
SSL_clear() resets the SSL object to allow for another
connection. The reset operation however keeps several settings of the
last sessions (some of these settings were made automatically during the
last handshake).
It only makes sense when opening a new session (or reusing an old one)
with the same peer that shares these settings. SSL_clear() is not a
short form for the sequence SSL_free(3); SSL_new(3);
....
