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.
