"The NYSE needs to restore the program trading cubs that were in place up until November 2007. Those trading curbs would do a LOT to slow down frenzied trading, especially now with the high-frequency trading done with supercomputers."

Does a trading curb mean I'm not allowed to sell my stock if the price has changed too rapidly? Not sure I like the idea of not being allowed to sell.

No, those old trading curbs were in place to stop the type of runaway programmed trading selling that happened in October 1987. The problem is that we need those curbs to be in place now given the serious potential for a runaway single crash.
