 348 Signals and Windows
 349 ===================
 350 The SIGHUP signal does not exist on Windows and does not need to be handled.
 351
 352 Windows handles SIGFPE and SIGSEGV signals as expected.
 353
 354 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 355 cause a new thread to be spawned. This may well result in unexpected
 356 behaviour by the single-threaded LyX.
 357
 358 SIGTERM signals will come only from another process actually sending
 359 that signal using 'raise' in Windows' POSIX compatability layer. It will
 360 not come from the general "terminate process" methods that everyone
 361 actually uses (and which can't be trapped). Killing an app 'politely' on
 362 Windows involves first sending a WM_CLOSE message, something that is
 363 caught already by the Qt frontend.
 364
 365 For more information see:
 366
 367 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
 368 ...signals are mostly useless on Windows for a variety of reasons that are
 369 Windows specific...
