pinocchio	stopwatch	--with-stopwatch	Select tests based on execution time

pinocchio-0.4.1/pinocchio/stopwatch.py

    def finalize(self, result):
        """
        Save the recorded times, OR dump them into /tmp if the file
        open fails.
        """
        try:
            fp = open(self.stopwatch_file, 'w')
        except (IOError, OSError):
            t = int(time.time())
            filename = '/tmp/nose-stopwatch-%s.pickle' % (t,)

int(time.time) is easily guessed, create a few thousand and you're
covered for the next few hours and can stop anyone from using stopwatch,
or you can just blow away files as usual =).

            fp = open(filename, 'w')
            log.warning('WARNING: stopwatch cannot write to "%s"' %
(self.stopwatch_file))
            log.warning('WARNING: stopwatch is using "%s" to save times'
% (filename,))

        dump(self.times, fp)
        fp.close()
