Can you look what's going on inside crypto/bio/bss_sock.c, function
BIO_sock_should_retry (which is queried by the function that BIO_write
ends up calling when that function decides whether to set the retry
flag)? There's some disabled code there; maybe switching it on again
helps here (which would mean that WSAGetLastError(), aka
get_last_socket_error(), returned 0 for that retry)?
