Question about memory management with bindings

[mantielero]

I am working with the bindings to MLT. You can create a number of producers: 
`newProducer`. Once used you would destroy them with: `close`. So the pattern 
needed would be something like: 
    
    
    p1 = newProducer()
    p2 = newProducer()
    ...
    ...
    p1.close()
    p2.close()
    
    
    Run

I am not sure about the proper way to handle this. I'd like to do this 
automatically (I understand this is how GC work).

Any recomendation?
