Have you tracked the source of this memory usage? Are you sure it's not
caused by the application?

That's already how libcurl works. Once it sends data, it's not kept
around any longer. If libcurl needs the data again, it will call the
CURLOPT_SEEKFUNCTION function rather than keeping it around.

Use valgrind or another memory usage tracker to find out exactly where
that memory is going. In the unlikely event that it turns out to be in libcurl,
then we here would certainly be interested in knowing.
