In order to stream-upload, QNetworkAccessManager requires a few guarantees 
from you and the receiving side.

You need to:
 - provide the exact size of the upload before it starts
 - set QNetworkRequest::DoNotBufferUploadDataAttribute in the request

If you can't do that, QNAM will need to buffer the entire content before it 
starts sending it.
