On Windows:

import std.stdio;

extern(C) int getch();

void main()
{
    stdout.setvbuf(100, _IOLBUF);
    string mystr = "Hello\n";
    fwrite(mystr.ptr, mystr[0].sizeof, mystr.length, stdout.getFP);

    // FPUTC('\n', cast(_iobuf*)stdout.getFP);

   getch();
}

Am I doing anything wrong there? That code as it is does not flush until
after a keypress (when the program terminates).  Uncomment the FPUTC call
and it does flush before the keypress.
