Narrative:

Although this wasn't a near miss, if I had followed the controller's instructions or ignored TCASII, it would have been. We were on a southerly vector off of the kayoh arrival into lgb. The controller called traffic at 1 O'clock moving to 11 O'clock 7500 ft (we were level at 8000 ft). He instructed us to descend to 4000 ft. While I was thinking about the 12 O'clock traffic (about 2 seconds) we immediately got a climb, climb. I kicked off autoplt and altitude hold and climbed. At about 8150 ft the threat disappeared. I notified ATC of our climb and that we were back level at 8000 ft and to confirm our descent to 4000 ft. His comment was roger. I informed him again that we had received a RA TCASII to climb when he gave us the initial descent instructions. Once again, all he said was roger! I definitely have more respect for TCASII now. I wish our company would put it on the radar display on non EFIS and on our CRT's on the EFIS aircraft.
