Description:
 def jumpTo(self, bytes):
 """Look for the next sequence of bytes matching a given sequence. If a match is found advance the position to the last byte of the match"""

        newPosition = self[self.position:].find(bytes)
        if newPosition > -1:
            # XXX: This is ugly, but I can't see a nicer way to fix this.
            if self._position == -1:
                self._position = 0
            self._position += (newPosition + len(bytes) - 1)
