hard to spot.

req.ssl_cipherlist binary
Returns the binary form of the list of symmetric cipher options supported by
the client as reported in the contents of a TLS ClientHello. Note that this
only applies to raw contents found in the request buffer and not to contents
deciphered via an SSL data layer, so this will not work with "bind" lines
having the "ssl" option. Refer to "ssl_fc_cipherlist_bin" which is the SSL
bind equivalent that can be used when the "ssl" option is specified.

# Wait for a client hello for at most 5 seconds

side state is there when SessionTickets are in use.
