Has anybody ported PyQt to DOS without my knowledge? ;-)

...and the thread disappears, when this method finish. 

This is by far the most frequent PyQt beginners failure:

You either need to keep a reference on the thread object 
(e.g.: s/thread/self.thread/)
or add a parent object to the ctor, as most Qt objects do.
How to do the latter is left as an exercise to the implementor.
