At first and unfortunately at last. Signals and threads in python is
pretty much a dead end; ask me how much time I've burnt on that trying
to get Ctrl-C to interrupt a computation in the gui multithreaded
IPythons used for interactive matplotlib plotting with any toolkit
other than Tk. It sucks. Big time.
Basically, Python won't let you send an asynchronous signal reliably
across threads even on *nix, let alone on win32.
