No, it doesn't use sendfile. libcurl supports too many options that conflict
with sendfile (e.g. various timeouts, read callbacks, progress callbacks,
encrypted data, compressed data, chunked transfers, etc.) that the percentage
of combinations of options where it could be used is vanishingly small.
