good catch, sounds OK to me.
My version has also a flaw left, i.e. if the parent receives an interrupt
during the single waitpid($child, 0).

Would it be OK that I exit with the return code of the sub method "$sub"
from the forked child as exit code?
This would be helpful as I'm using the exit code to pass some information
to the parents caller, which is for this specific case easier than opening a
pipe and parsing some text there.
