29 When the parent Parallel::ForkManager object forks a child process, its
30 forked incarnation consumes this role. The role doesn't do much: it
31 changes the returning values of "is_child" and "is_parent" in the way
32 you'd expect, change "start" so that it'd die if called from within the
33 child, and change the implementation of "finish" to potentially send
34 data back to the parent process.
