Each time load() runs it creates and uses a new object. The "leak like" 
behaviour is the bunch of object in memory.

'del' does actually delete the object like in C++. 'del breaks the reference 
from that variable to the object. When python feels like it, it will clean up 
and free memory.

QFileDialog.getOpenFileName doesn't create a new object. Therefore you don't 
get a build up of objects.
