So you could do something like give every thread a different default stderr,
stdin, and
stdout which would be in the thread local area.  Calling printf would
automatically
use the calling thread's stdout and calling perror would use the thread's
stderr.

I'd thought about this in conjunction with banked memory before but for
systems without
it I didn't see the real use.  What you suggested might be a good idea
though.
