This is a bit of a problem for older clients because the specification
requires sending a no_renegotiation alert. OpenSSL clients before 0.9.8m
just ignore this alert and carry on expecting the handshake to continue. This
never happens and the "hang" is the result.

Presumably any client could just connect to the server and partly complete the
handshake and get the same effect in any version of Apache and mod_ssl.
