[issue8240] ssl.SSLSocket.write may fail on non-blocking sockets

[Cyril]

Cyril <cbay at excellency.fr> added the comment:

I forgot to talk about the conditions in which I stumbled upon that bug. I use a cStringIO.StringIO as a send buffer. When the socket is ready to send data, I call ssl_socket.send(send_buffer.getvalue()).

Unfortunately, two consecutive calls to send_buffer.getvalue() may return a different object (i.e. a string with a different memory address).
