## fork.swift
// Note: calling fork() can be unsafe and dangerous, that
// is why Swift doesn't let you invoke it directy. Be very
// careful about how you use fork(). For some more details,
// see https://www.evanjones.ca/fork-is-dangerous.html and
// http://www.sealiesoftware.com/blog/archive/2017/6/5/Objective-C_and_fork_in_macOS_1013.html
