Fork always seemed conceptually terrible even when I first learned about it.. If you want to do one thing (start a process) you should not have to use a mysterious incantation that does a different unrelated thing (forks your process) in order to do it.

I am curious about what the best way to handle the example in the article of one process spawning many git subprocesses is. Surely it just doesn't make sense to repeatedly start git from scratch in the course of a long-running parent operation. What's the low cost abstraction for the same result, though?
