Has anyone an example for wanting to fork? Most use cases seem covered by either threads or fork+exec process spawning.
The example given by the author:
make it practical to introduce concurrency after development, rather than designing it in from the start
seems risky to me: Even if you're safe from other threads, there is a lot of other unknown state like fd's still inherited. And concurrency can be introduced after development, e.g. by using message passing. So going all the way threaded or re-execing yourself seem both safer to me with no real downsides.
