my first D program, what is wrong with it?

[dominik]

ok, I've just unzipped dm and dmd, and I have tried to write my first 
trivial D program - just to get started (below is the code I wrote). It 
works, from the first try :) However, it behaves em weird.
First writefln works like it is supposed to, last one also, however writef 
should just write in place haaaa and the number (hence the \r). But, when 
printing in place is done, and the last writefln fires off, line where 
writef wrote to disappears. How, why?

I'm on windows XP if that matters
----------------------------------------------
import std.stdio;

int main(char[][] args)
{

    writefln("===================");
    for (int i = 0; i < 50000; i++) {
      writef("haaaaa ", i, " \r");
    }
    writefln("===================");

    return 0;
}
