This is expected. When a pty is allocated, all of stdin, stdout and
stderr point to the pty (see "ls -l /proc/$$/fd" on Linux). Being on
the other side of the pty, sshd has no way to determine which fd the
child process issued the write() to. Changing the fd allocation so that
stderr was a pipe instead of a pty would be a significant departure
from standard practice and would probably break quite a few things.
