Guess what?  _get_dev_info(0) == 0 on *ANY* redirected input on Windows NT 4.0
unless it is from CON.  So these weird handles appear on NT 4.0 also.

This is also true for a real pipe on NT - it does not need to go to a 
temporary file.  You can't seek on pipes - but it appears these strange
handles support some limitied seeking in a strange way.

For example, I can do dir | test and see the same strange behavior, but
no file is created on disk.
