stdio line-streaming revisited

D programmers sometimes like to call 3rd party code written in other 
languages, and pretty much any interop in D has to happen via C 
compatibility.  E.g. pyD.  So I'm guessing if my D code calls on some 
Python code that prints to the console that somewhere down the line that 
eventually ends up on C's stdout.  I could be wrong, but at least that's 
why I *think* Andrei and Walter keep saying that C compatibility is 
important.

Andrei -- by "compatibility" does that mean if I rebind stdio/stdout to 
something different that both D and C's output go to the new place?  Or 
is it still necessary to rebind them individually?  I did this once for 
some legacy code in C++, and found that I had to rebind 3 things: the C 
streams, the C++ old-style streams from <iostream.h> (was under MSVC 6), 
and the new-style C++ streams from <iostream>.    And then I had to do 
the interleaving myself, which didn't really work (because all the 
streams were just writing to output buffers individually).  If what 
you're talking about with compatibility would avoid that kind mess, that 
is certainly be a good thing.
