Interesting Thread.sleep error in Mono-D

[Jeremy DeHaan]

I was playing around with various parts of D today and I got this 
very strange error when I call Thread.sleep() in my code in 
Mono-D.

First, I'll post the code:

module main;

import std.stdio;
import core.thread;

void main(string[] args)
{

	int i = 0;
	
	while (i < 10)
	{
		writeln(i);
		Thread.sleep(dur!("msecs")(500));
		i++;
	
	}
	

     // Lets the user press <Return> before program returns
     stdin.readln();


The funny thing is, the code compiles fine. When I run it via the 
console(in Windows) it runs as expected. When running it through 
MonoDevelop/Mono-D, however, I don't see any output until the 
program stops running and then I see it all at once along with 
this set of messages.

Am I actually doing something wrong? Or is this just something 
going on with Mono-D?
