Or simply don't buffer. Any call you get, flush the C buffer and 
write the D stuff immediately.

Remember, this code branch is only called if we already know it 
is an interactive console. They're usually flushed frequently (at 
least at every line) anyway... so especially with writeln / 
writefln those are virtually guaranteed and certainly expected to 
flush at the end anyway. I really don't think any performance 
concern would be significant.
