Redefining *standard-output* on Windows

[il71]

SBCL 1.3.8
Windows 10, x86-64

This works on Linux, but fails on Windows:

(setq *standard-output*
      (sb-impl::make-fd-stream 1
                               :output t
                               :buffering :full
                               :external-format :ascii))
(format *standard-output* "qwe")
(finish-output *standard-output*) ; <--- this one

#<THREAD "main thread" RUNNING {10056C6493}>:
  Couldn't write to #<SB-SYS:FD-STREAM for "descriptor 1" {1007AF80E3}>:

That's because this code is wrong for windows, and it's internal API, don't use it.

I see. Can you suggest what to do on Windows to speed up output to stdout?
