For the record, though I think you realise this, *both* the SSL_read()
or SSL_write() and the following SSL_get_error() need to be protected
as a unit by the *same* instance of the locked mutex. It would not
be enough to lock these separately.
ret = SSL_read(ssl, ...);
ret = SSL_write(ssl, ...);
if (ret <= 0)
err = SSL_get_error(ssl, ret);
/* Handle EOF and errors */
