therefore it is not a proper subsystem, but it will be converted to native as soon as it begins working. It probably does NOT work under ROS. I tested it under NT 4.0 SP 6a. To see what it creates in the system name sapce, run WinObj, and HandleEx. If you run csrterm.exe, it tries to connect to psxss.exe, but then dies because the API to tell psxss to create a PSX process it not implemented yet. PSXDLL.DLL will connect to \POSIX+\ApiPort (initial code in psx/lib/psxdll/misc/init.c is mute). svn path=/trunk/; revision=2841
