Added an interface for noticing new thread creation.  At this point, I only turn it on when 
we are requesting a single thread to run.  May seem like a silly thing to do, but the kernel 
on MacOS X will inject new threads into a program willy-nilly, and I would like to keep them
from running if I can.
