Description

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

Name

       Parallel::ForkManager::Child - role adopted by forked Parallel::ForkManager processes

Synopsis

          use 5.10.0;

          use Parallel::ForkManager;

          my $fm = Parallel::ForkManager->new;

          say "parent does not consume the child role: ", $fm->does('Parallel::ForkManager::Child');

          $fm->start_child(sub{
               sleep $_;
               say "but the child does: ", $fm->does('Parallel::ForkManager::Child');
               say "child $_ says hi!"

          }) for 1..3;
