the -T test just tries using a variety of buffer sizes during the data
transfer, followed by a cancel (instead of completing the scan) IIRC.
This might put some scanners/backends into a funk, as they dont
properly implement the cancel.

i would not assume that every scanner/backend combination will act
properly with -T.
