Sounds like that was part of the direction given, not a choice made (by 
the recipient of the direction).  You can't necessarily expect sense in 
what you're told to do.

On the Put_Line issue, why not simply wrap it in a protected object, and 
change Ada.Text_IO ref's to that object?  That won't help with the 
sequence-of-calls issues; you'd need individual protected calls for each 
sequence.
