    I'd argue against general thread cancellation.  Inter-thread
signals, though, have safety problems no worse than the first-thread
only signals we have now.  You're allowed to raise an exception
in a signal handler, which is effectively thread cancellation.

    So right now, you can kill the first thread from another thread.
