It sounds like the negotiation code in OpenSSL is looking for a block 
of bytes longer with a longer initiation list than the client provides for
an SSLv3 or SSLv2 handshake.

This means, since they weren't stacked in the best order, that OpenSSL
can only finish handshaking after the client times out to Apache.

If you want to help the OpenSSL team fix this, you might use a very
limited list of one additional protocol plus SSLv2 or SSLv3.

Then see which combination of two ciphers causes everything to choke
waiting for the timeout.
