type. The destructor closes handles to the child process when the

required to call wait_for_exit to clean up resources."
Does this mean child *is* copyable on other platforms? So the class has
entirely different semantics on different platforms?

I still don't get why you're letting this behaviour vary between
platform. Sure, the underlying system calls have different defaults but
they are both capable of both behaviours. The whole point of a
platform-independent library is to align such variation.
