   True. So what we need is to add a function in the testing framework
so that tests can get argc/argv/envp. Seems like a reasonable approach.

   It should have the same stdout as the parent, unless you explicitely
nuke them when calling CreateProcess.

   Yes, the child should have an exit code that indicates success and
another one that indicates failure. The parent checks that and returns
success or failure as appropriate.
