> I cannot explain why stdin might be in non-blocking mode, but it was,
> and so sometimes expect would miss the username/password strings. I
> can only put this one down to deep crackfulness on the part of tcl,
> expect, apache, or php, and express my strong desire to never know
> what is going on there. Understanding this can only lead to
> pain. Forcing stdin into blocking mode ensures that it always works.

> The exp_continue is necessary because otherwise, if expect sees
> $fingerprint_string, it does not bother looking for $password_string
> or sending the old password. Obviously nobody ever tested this, it
> can't ever have worked.
