Pong is an ultra-cute demo but exposes some issues on Edison (MRAA or Quark app. ?)

Thanks for this extremely cute demo for the OLED block.

Just like to report that I've seen at least 2 issues exposed and would like to help fix them (but not sure if this is the best place to start ?)

• The oled_pong app helps chew up 1 of the 2 Edison CPUs when running as below
• After 5-6 hours running there's usually a Linux crash-restart as below
