Is this a bug in the concurrency lib or am i using it incorrectly?

[Gary Willoughby]

I was hoping the below example would display 'hello world' but it 
only displays 'hello'. Is this a bug in the concurrency lib or am 
i using it incorrectly?

import std.stdio;
import std.concurrency;

void writer()
{
	try
	{
		while (true)
		{
			receive((string s){
				writefln(s);
			});
		}
	}
	catch (OwnerTerminated ex)
	{
		// die.
	}
}

void sender(Tid writer)
{
	send(writer, "world");
}

void main(string[] args)
{
	auto writer = spawn(&writer);
	send(writer, "hello");
	spawn(&sender, writer);
}
