Yep. Unicode *input* streams need to be buffered, but *output* can
always be insta-flushed. The only significance of Unicode to output is
that a single character may cause multiple bytes to be output; and
since output can block for even a single byte, it should be no
different.
+1 for making sys.stderr unbuffered.
