The inconsistency here is that the new process created contains an image
of a process state that looks like it has perhaps multiple threads running.
Each thread in the parent has its own stack. Which stack will the one new
thread in the child be using? There will at least be a lot more stuff the
child process has to clean up, like all the descriptors in use by all the
threads of the parent.
