    Thanks, I've seen that. However, in my design processes in my head, I always prefer to keep thread shared variables read-only from the outside. In otherwords, one thread should not be able to change a variable in another thread, without the target thread knowing(or asking for it). This is better for security, and avoids all chances for a run away condition, where threads are all trying to lock and change a var at the same time....constantly looping....and having their change thwarted millisecs later by another thread. This requires you to have a thread that acts as a main controlller..... like a parent, keeping order among the child threads.
