I wish people would stop pointing at the Linux subsystem and using it as an example of the stuff Windows in general could do. The Linux subsystem is a subsystem. In NT terminology, that makes it practically a container. It's disconnected from the rest of the system. It can interact with the win32 world in only a few constrained ways. You can't deliver SIGWINCH to a win32 process!

Actually, the second POSIX subsystem could deliver signals to Win32 processes. Who pointed at the Linux subsystem, by the way?
