What kind of non-blocking I/O do you use, O_NONBLOCK or something
else? Can you debug inside the BIO library (crypto/bio/bss_sock.c)
what is going on --- does read() (which is called 'readsocket' in
there, see e_os.h), return -1, what does errno ('get_last_socket_error()')
look like in BIO_sock_should_retry, what happens in
BIO_sock_non_fatal_error?
