If you have it in non-blocking mode, try to read some data from it.
If it is closed, you should get back 0, or a -1 with error other than
a 'retryable'. BIO_sock_should_retry(int error) has all (I think) of
the cases covered. If you pass 0 or -1 as the 'error' code to check,
this function will use the relevent 'errno' or WSAGetLastError() call
depending on unix or windows to lookup the error code.
