No matter how many times I've been over it, I always get confused when professors try to introduce process handling in a Systems class. At least the terminology is entertaining. Parents beget children using forks. For the sake of cleanliness, children should die before the parents, at which point, the parent in question should reap its children promptly, lest it leave zombies behind. If you're not clean, the Initial Process will have to adopt the orphans (and deal with the aforementioned zombies, which you cannot kill). And these conversations invariably lead to a discussion of pipes, and how you have to flush them frequently to avoid corruption. This knowledge, of course, is just to enable me to make a shell.
Um, yes. This is all true.
