 If there is already a session set inside B<ssl> (because it was set with
 SSL_set_session() before or because the same B<ssl> was already used for
 a connection), SSL_SESSION_free() will be called for that session.

+
+SSL_SESSION objects keep internal link information about the session cache
+list, when being inserted into one SSL_CTX object's session cache.
+One SSL_SESSION object, regardless of its reference count, must therefore
+only be used with one SSL_CTX object (and the SSL objects created
+from this SSL_CTX object).
