Ok, you should have mentionned that since the beginning :) All Stephen and I were trying to tell you, was that in some cases using SSL_read and SSL_write, you could end up having two threads reading from the same SOCKET. That's why I preconized some subclassing to "protect" the access to SSL_read and SSL_write.
