Hash :9b273824 Message :move redirect to UserProxy and introduce write_error.
redirect is only called thru a user, so have the error message be
more helpful in telling which user can't perform the redirect.
likewise, write_error should tell which user is involved.
don't wrap redirect_fh in run_as, because we're not opening any
new file.
