perl-Parallel-Runner

There are several other modules to do this, you probably want one of them. This module exists as a super-specialized parallel task manager. You create the object with a process limit and callbacks for what to do while waiting for a free process slot, as well as a callback for what a process should do just before exiting. You must explicitly call $runner->finish() when you are done. If the runner is destroyed before its children are finished, a warning will be generated and your child processes will be killed, by force if necessary. If you specify a maximum of 1 then no forking will occur, and run() will block until the coderef returns. You can force a fork by providing a boolean true value as the second argument to run(), which will force the runner to fork before running the coderef; however, run() will still block until the child exits.
