Besides the syntax, there is another thing to be aware of: If there is a
pipe from child -> parent (write -> read) and after the parent dies, the
child writes to the pipe, it will receive a SIGPIPE and die, too, if it
doesnt't catch this signal.

It means if whatever flag to enable setsid() is set, the user must carefully
think about adding For Read/Write/Input/Output.
