Don't do anything to that pointer, because when the callee (the second app)
quits, the system automatically frees that pointer. There's no way to
prevent it from doing so. (If you need more control, pass the info in a
handle and pass a pointer to a small buffer which contains that handle...
having set the owner of the handle to zero as well.)
I'm pretty sure this is covered in the docs and/or FAQs, but I see it isn't
in the reference entry for SysAppLaunch. I'll ask for it to be added,
since that's the most natural place to say it.
