Unbuffered output would perform badly, especially if you are writing 
characters at a time (which is what formattedWrite does). But I think 
this would solve the interleaving problem.

Honestly, I think it sounds horrible to have yet another special case 
for this specific situation. But also, I almost never use Windows for D 
work, so I'm fine if you want to duct tape some more cruft onto that 
branch. std.stdio is already a pretty big mess.
