I've just checked the definition of unsetopt and it only works for
certain options:

    /* FIXME: implement more options. Have to carefully check lib/url.c in the
     * libcurl source code to see if it's actually safe to simply
     * unset the option. */
    switch (option)
    {
    case CURLOPT_SHARE:
        SETOPT((long)0);
        Py_XDECREF(self->share);
        self->share = NULL;
        break;
    case CURLOPT_HTTPPOST:
        SETOPT((void *) 0);
        curl_formfree(self->httppost);
        self->httppost = NULL;
        /* FIXME: what about data->set.httpreq ?? */
        break;
    case CURLOPT_INFILESIZE:
        SETOPT((long) -1);
        break;
    case CURLOPT_WRITEHEADER:
        SETOPT((void *) 0);
        ZAP(self->writeheader_fp);
        break;
    case CURLOPT_CAINFO:
    case CURLOPT_CAPATH:
    case CURLOPT_COOKIE:
    case CURLOPT_COOKIEJAR:
    case CURLOPT_CUSTOMREQUEST:
    case CURLOPT_EGDSOCKET:
    case CURLOPT_FTPPORT:
    case CURLOPT_PROXYUSERPWD:
    case CURLOPT_RANDOM_FILE:
    case CURLOPT_SSL_CIPHER_LIST:
    case CURLOPT_USERPWD:
        SETOPT((char *) 0);
        break;

    /* info: we explicitly list unsupported options here */
    case CURLOPT_COOKIEFILE:
    default:
        PyErr_SetString(PyExc_TypeError, "unsetopt() is not supported
for this option");
        return NULL;
    }
