Ok. BTW, what happens exactly when you try and shut down a Mac? On a UNIX system all the processes are sent SIGINT or something, at which point they should enter a controlled shutdown procedure.
The OS X desktop uses Apple Events to send shutdown requests to applications - unlike signals, these can be responded to in-band. In a Cocoa application, this shows up as an applicationShouldTerminate: message to the NSApplication delegate.
