 * Run the core CPU loop

 * little bit faster than SingleStep, and should be pretty much equivalent. The number of
 * instructions chosen is fairly arbitrary, however a large number will more drastically affect the
 * frequency of GSP interrupts and likely break things. The point of this is to just loop in the CPU
 * for more than 1 instruction to reduce overhead and make it a little bit faster...
