Enable default object tracking no Mac
Enable default object tracking no Mac

We had trouble with base_unittests before, so we
ifdef'ed out the larger landing.  This tiny
switch CL will turn it on for the Mac, but can
be quickly reverted if there is a problem.

Scott Hess was able to debug and identify the
cause of the problem (yeah Scott!!!!).  I think
the code we landed corrects for the issue he identified,
and this should prove it (or get reverted trying).
