When you say "objects", you're talking about your own code, right? I've written the inverse (multiple threads waiting for a signal from one thread) as part of an emulation of the Linux "waitq" interface, but the concepts should work fine for you. That used the Mach thread interface. Basically, in the waiter thread you do: res = assert_wait(addr, state); if (res == THREAD_WAITING) thread_block(THREAD_CONTINUE_NULL); (If you want a timeout, you can call assert_wait_deadline() instead). And in the wakeup threads, you do: thread_wakeup_one(addr); Obviously the key here is to have all of your other "dispatcher objects" make sure they call thread_wakeup_one() on the right addr. --Ken _______________________________________________ Do not post admin requests to the list.

I think your best approach would be to enable the Guest user and then set up Parental Controls for that user to limit what they can do once logged in. Running Safari without creating a proper GUI login session is going to be virtually impossible, and the alternative, creating a custom GUI login session, isn't any easier.
