+
+SSL_free() also calls the free()ing procedures for indirectly affected items, if
 applicable: the buffering BIO, the read and write BIOs,
 cipher lists specially created for this B<ssl>, the B<SSL_SESSION>.
 Do not explicitly free these indirectly freed up items before or after
 calling SSL_free(), as trying to free things twice may lead to program
 failure.
 
+The ssl session has reference counts from two users: the SSL object, for
+which the reference count is removed by SSL_free() and the internal
+session cache. If the session is considered bad, because
+L<SSL_shutdown(3)|SSL_shutdown(3)> was not called for the connection
+and L<SSL_set_shutdown(3)|SSL_set_shutdown(3)> was not used to set the
+SSL_SENT_SHUTDOWN state, the session will also be removed
+from the session cache as required by RFC2246.
