Originally we simply passed in the hProcess obtained by CreateProcess(). Unfortunately that left the completion callback vulnerable to the business logic closing the handle, meaning we could not obtain the child process termination code. Duplicating the handle and passing the duplicate solves that issue. Also, the object_handle must survive until its async_wait() call has called its completion handler. Otherwise the handler is called too soon (immediately!) while the child process is still running.

This pull request depends on #10. That changeset displays as part of this comparison.
This PR provides a high-level feature -- asynchronous child-process termination notification -- using two distinct platform-specific initializers with the same name and signature, permitting portable consumer code.
