Whew.

I squished this bug halfway. Officially, we cannot use setvbuf after any
operation on the stream, and as we're dealing with clones of the
stdout/stderr stream, we cannot use setvbuf at all - /actually/.

Practically, it appears to work if we use fflush() first, which is what
we're doing, for performance reasons.

This bug had been bothering me for quite a long time. Good riddance (I hope).
