Is this likely to get into firefox any time soon? I would be so, so happy.

Oh, actually, I wonder if the "transfer" semantics of ArrayBuffers wouldn't
give us the ability to emulate the exchange heap more accurately:

Long story short: you can dynamically emulate unique ownership of binary data and
transfer it between workers without copies. The sender's reference to the data becomes
"neutered" so that it's unable to view the data after the send. Of course, Rust
would guarantee it never even tried.

That would result in a very different performance model, since Rust expects to
be able to create several metric craptons [1] of concurrent tasks, whereas the
number of workers you can create is much smaller. But who knows, it might still
be interesting enough to be useful for some kinds of programs; ClojureScript is
making progress as a single-threaded dialect of Clojure, after all.
Not to mention that we would have to deep-copy all messages.
