As you can see my sample program is *very* simple.  I havent
explicitly turned anything on.  Also, does vtk use threads underneath
so even if you dont create a threaded application VTK does threads
internally to do things?? I can see that the libraries are linked to
libpthread but am not sure if this is really used.

Sure.  It might not cause a core dump and might cause BadRequest or
other errors instead.
