Fix crash rendering grass_wind.blend from regression tests. The real

problem is that where_is_object is being called from multiple threads
but is not thread-safe, added a note about this problem, this commit
only solves the crash. Also remove the pushdata/popdata mechanism
that was being used here, using this kind of system is bound to give
problems with threading.
