  SVN rev 207329 on 2010-04-28 15:38:01Z by attilio
  
  - Extract the IODEV_PIO interface from ia64 and make it MI.
    In the end, it does help fixing /dev/io usage from multithreaded
    processes.
  - On i386 and amd64 the old behaviour is kept but multithreaded
    processes must use the new interface in order to work well.
  - Support for the other architectures is greatly improved, where
    necessary, by the necessity to define very small things now.
  
  Manpage update will happen shortly.
