For everything else other than Cocoa and Carbon applications that receive AppleEvents, when the computer is shutdown, everything else is sent a SIGKILL by launchd, just like any other Unix system (launchd takes the place of the init daemon seen on other Unix systems). Semantics for BSD signals are described in the man pages (kill, signal, etc.). SIGINT is like hitting Ctrl-C at the terminal to stop a shell process. Processes can ignore a Ctrl-C. SIGKILL is non-ignorable.
For the record, this is incorrect. Each process is sent a SIGQUIT. It would be extremely bad for launchd to send a SIGKILL as a matter of course. You might as well just shut your computer down by turning off the power, if that was the case.
