I've tested it out with DMD 2.053 on Windows XP.

import std.stdio;
import core.thread;


void main()
{
    version(WIDE)  // Will flush during write
        wstring mystr = "Hello\n"w;
    else // Will not flush
        string mystr = "Hello\n";

    write(mystr);

    Thread.sleep( 70_000_000 );  // 7 sec
    stdout.flush();
}


Also, there's nothing in the C standard that says, stdout must be buffered
this way or that way or even buffered at all.  I believe you can safely
assume that stdout is line-buffered in Linux, though, but I'm not sure.
