Actually, Ctrl-C handling on Windows is very similar to Posix.  The
only major problem that I'm aware of is that the Ctrl-C handler runs
in a separate thread, so a single-threaded program suddenly becomes
multi-threaded, and in particular one can have race condition between
the main thread and the signal thread.
