If you execute bb.py, let it running for a while and then press Ctrl+C
then the Python will terminate safely and you will get the following
output on your console:

E:\KkWebrman\Instalace\Tmp>bb.py
init
parsing time...
...done
started
parsing time...
...done
parsing time...
...done
finishing
done

E:\KkWebrman\Instalace\Tmp>

However, if you execute aa.py then it will not terminate by Ctrl+C and
you will get the following output on your console:

E:\KkWebrman\Instalace\Tmp>aa.py
init
parsing time...
started
finishing

The aa.py simply imports bb.
