How could signal module be used here? Doesn't it only contain signal constants, a function to register signal handlers, and some UNIX only functions to set timers and alarms?

It seems to me that really supporting `send_signal` on any platform would require `os.kill` (currently missing) and `Popen.pid` (always None). I know supporting these on JVM is far from trivial, but on the other hand these features would be very useful also independently.

I totally understand if fixing this is impossible in Jython 2.7.0 timeline. In that case it would probably be a good idea to change to code to just this:

    def send_signal(self, sig):
        if sig == signal.SIGTERM:
            self.terminate()
        raise ValueError("Unsupported signal: {}".format(sig))

It seems that JVM actually sends SIGTERM on POSIX when calling `process.destroy()` (like `self.terminate()` does), and on Windows sending SIGTERM is anyway just an alias for terminating the process also on CPython.
