MySQL SSL Support

In my wp-config.php file I add
define('MYSQL_CLIENT_FLAGS', MYSQL_CLIENT_SSL);
so all database connection happen over SSL. How can I add that setting to HyperDB?

I found where I can hack into db.php and stick it on the end of the connect_function, but that seems to only work for the master.
