It is not that we are failing to recognize Darwin, it is that Darwin is
falsely claiming to be something else.

No, I'm seeing an NSLinkModule -> memcmp crash.  memcmp() is crashing
because it is being passed a null pointer, and the pointer in question
is null because ps_status.c zeroed it via "argv[1] = NULL".

I modified ps_status to use the correct status update method
(PS_CLOBBER_ARGV) but it still failed :-(.  It sorta looks like
something in the dynamic loader may be relying on a stale copy of
the "environ" pointer ... does that ring a bell at all?
