In kern_threads.c, in function thread_export_context() it first does a copyin() of the context storage area. I think this is un-needed (and a complete waste of cycles) but I am not sure if there is some strange condition regarding floating point registers or something that may want this.. Dan, Jon, David? do any of you have a good reason why I shouldn't remove the copyin().??
