[image scaling example freezes|https://forum.qt.io/topic/119796/image-scaling-example-freezes-qt-concurrent-issue]
The official Image Scaling Example freezes if 12 or more files are selected.
If I disable CPU SMT feature, then the app freezes when 6 image files are selected.
If the number of image files is less than the number or CPU logical cores, the app works normally.
Debug shows the all work threads block.
