What possible side effects do you see here? What problems could it cause?
So far I've tried to copy a lot of files in parallel, arbitrarily drop

The file is either transferred in its entirety or (in case of dropped 
connections) not.

I couldn't find a complete example for this task, so it would be nice if 
somebody more experienced could share the secret of doing this right and
