Different threads can share arbitrary values, including mutable objects. Different places cannot share anything (except for some specific kinds of atomic-data vectors). So, moving a thread from one place to another is difficult in general, because starting the thread on a different place would change the kinds of values that it can share with other threads. Threads can send and receive place-style messages within a single place. Across multiple places, though, a thread handle is not one of the things that can be sent across a place channel; threads in different places exchange messages only across a place channel. ____________________ Racket Users list: http://lists.racket-lang.org/users
