I think the stream (handle) point of view worked, but somehow msvcrt 
doesn't initialize stdin/err/out when the app is in GUI mode. It may 
work if the app would close 0,1,2 and reopen them on standard handles

the only point is that we don't have a consistent basis across platforms 
were we start the tests from:
- all tests programs are CUI exec
- but, we don't know if it's attached to a console or not
- if attached to a console, we don't know whether other processes are 
outputting to the same console (which could impact the tests...)
- ...
