Command line and GUI tools : need a single threading solution

How well mixing the two threading APIs works depends on version numbers. A
PyQt generated with SIP v4.x (rather than SIP v3.x) with Python v2.4
should be Ok.

Using QThreads only should work - just tell the QApplication ctor that you
have a console application.
