Is this an OpenSSL bug? I think there's an OpenSSL bug I am hitting as
well with Firefox 3.x (even using the ssl_protocols workaround) - if
this is a bug in OpenSSL I'd like to go yell at them for both... :)

I agree.

I've updated the wiki with this information.
http://wiki.nginx.org/NginxHttpSslModule#ssl_session_cache

Does it still accept two parameters as shown int he example on the
wiki? I want to make sure that is still legitimate. I assume that
means it will use the first cache and fall back to the second if it is
full or something?

Please verify my changes are correct. I don't want to be putting up
incorrect information :)
