You can have a look at DistributedObject. I think you can publish a

DO might be overkill for this scenario. The background thread really
just needs to run a while() loop that waits on a condition-lock,
then draws. The main thread's -drawRect: method just sets the
condition on the lock to trigger the background thread.
You're right for the.
If more information needs to be passed to the thread, you can use a
producer/consumer queue, but unfortunately Foundation doesn't come
with one of those built-in; there must be source code for one lying
around, though.

You're too. The Cocoa Threading Programmming Guide shows a way to
implements producer/consumer using NSConditonalLock.
