    For the benefit of googlers, this is due to a bug in pty handling present
    in many SysV derivatives. The workaround (for 3.6.1p2) is to manually
    add "#define STREAMS_PUSH_ACQUIRES_CTTY 1" to config.h and recompile.

    The next release of OpenSSH will do this automatically for Reliant and
    for NCR MP-RAS which has the same problem (if anyone with these
    platforms tests the patch, that is, otherwise they will be just as
    broken).

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
