I don't see a hang in this example, it writes 3 lines to the child and flushes and closes the output stream.
`cat` will see end of file and exit.
Almost all processes started will exit when they've done what they are supposed to.
A more defensive example would give the impression that every use of a process should follow the same pattern.
It adds a lot of boilerplate to schedule an interrupt and then cancel when the process exits.
