I think the problem is: P::FM doesn't start the next process exactly when the previous ends because the sleep granularity used is 1 whole second. Try setting `$pm->set_waitpid_blocking_sleep(0);` and re-run the 4,8,16.32,50... With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". I'm with torvalds on this In the absence of evidence, opinion is indistinguishable from prejudice.
