That makes sense, thanks.

Adding a note in case anyone stumbles across this with a similar 
problem:
Adding `stdout.setvbuf(0, _IONBF);` to both the main and DLL will 
cause D to autoflush after every write call without requiring a 
manual flush (which seems to happen quite often when running 
under anything other than a basic Windows command prompt).
