WARNING: THIS WILL *may, depending on graphics card, ram and your CPU* LAG YOUR COMPUTER! Use at your own risk. Just type y in the prompt.
TL;DR: It would take hours of staring at the project for it to work on post 2000 computers. | FBfail is possible, how ever it clones the clones so it's very unlikely that it wouldn't work. It's just a warning because depending on your computer it wont be able to make any more fork bombs past 300. It would take HOURS to crash. If you had a Pentium 2 with like, a gig of ram then it would crash INSTANTLY. And you have to leave it open so that it stresses the graphics card. So it wouldn't do much to the average modern computer, even lower end laptops.
