I'd say there is no problem. It just *appears* to be one. The first
program finishes, and the shell displays its prompt, while the child is
still outputting things. I bet you can see the stef at stef-desktop...$
somewhere in the output.
It's like executing:
the shell prompt is shown as soon as the ls (background) process starts,
but gets lost in the output.

Calling wait in the parent script would prevent it to finish before the
child, avoiding the issue.
