I would suggest you look at perlipc. If you use certain forms of open, you can accomplish one or two of your tasks (fork or fork and exec), as well as get the pid of the child back. This might make monitoring easier as well, depending on how you are going about that (checking the stdout), if not then consider opening and dupping a filehandle for STDIN before you open your child.
