The second was that renegotiation was just plain broken. I can't
believe I didn't notice this before -- once 64k was sent to/from the
server the client would crash. Basicly, in 7.3 the server SSL code set
the initial state to "about to renegotiate" without actually starting
the renegotiation. In addition, the server and client didn't properly
handle the SSL_ERROR_WANT_(READ|WRITE) error. This is fixed in the
second patch.
