Threads Question

[Jorge M. Pelizzoni]

Yes, it is possible that T takes control before Y is bound to 5. But, if
your concern is that T, at some point, needs Y bound, you are actually
not concerned, because it will (implicitly) block until Y gets bound
(that's why Oz is said to be dataflow-oriented). Now, if you really have
a race condition there, you won't be able to avoid explicit
synchronization constructs (locks and the like).

it's
