 =head1 DESCRIPTION
 
 SSL_read() tries to read B<num> bytes from the specified B<ssl> into the

 peer requests a re-negotiation, it will be performed transparently during
 the SSL_read() operation. The behaviour of SSL_read() depends on the
 underlying BIO. 
 
 If the underlying BIO is B<blocking>, SSL_read() will only return, once the
