Spork: A posix_spawn you can use as a fork

In the over 50 years since its introduction, the fork system call has evolved from a simple system call into a slow, complex behemoth that pervades many operating system (OS) primitives and hinders the implementation of superior OS concepts. There exists a multitude of issues with the fork system call, and programmers are encouraged to use alternatives such as posix_spawn. However, migration to new APIs is not happening, as shown by the analysis in this paper.
