QtConcurrent is for example used to load GPX files in parallel in GPSSync:

http://lxr.kde.org/source/extragear/graphics/kipi-plugins/gpssync/gpsdataparser.cpp#97

QtConcurrent documentation:

http://developer.qt.nokia.com/doc/qt-4.8/threads-qtconcurrent.html

@Lukas: Last time I looked, QtConcurrent only offered to automatically use the
number of available cores, and also did not allow you to change the priority of
the thread. Maybe KDE's threadweaver [1] allows you to do that.
