use timely_communication::Allocate.

configure for two threads, just one process.
let builders = timely_communication::allocator::process::Process::new_vector(2).

initializes communication, spawns workers
let guards = timely_communication::initialize_from(builders, Box::new(()), |mut allocator| {
println!("worker {} started", allocator.index()).

allocates a pair of senders list and one receiver.
let (mut senders, mut receiver) = allocator.allocate(0).

send typed data along each channel
use timely_communication::Message;
senders[0].send(Message::from_typed(format!("hello, {}", 0)));
senders[1].send(Message::from_typed(format!("hello, {}", 1))).

no support for termination notification,
we have to count down ourselves.
let mut expecting = 2;
while expecting > 0 {
allocator.receive();
if let Some(message) = receiver.recv() {
use std::ops::Deref;
println!("worker {}: received: <{}>", allocator.index(), message.deref());
expecting -= 1;
}
allocator.release();
}

optionally, return something
allocator.index()
}).

computation runs until guards are joined or dropped.
if let Ok(guards) = guards {
for guard in guards.join() {
println!("result: {:?}", guard);
}
}
else { println!("error in computation"); }
