A global fixture doesn't work quite the way you think it does.  It is
possible for test cases to execute before your global fixture has been
instantiated.

That is, a global fixture is only "global" for a single translation
unit and not multiple translation units.  Therefore, I recommend using
a custom implementation of main instead of a global fixture, since
this *really* should only be done once per process and not the way
global fixtures work.
