I cant't find your later mails on the subject in the cygwin-developers
list archive, but I vaguley remember that this was discussed at one
point and nobody had an idea how to implement it without turning the
code upside down.  You're familiar with the fhandler_console code as
well, so maybe you have an idea now how to implement this?
