rdtsc fun
// What the fuck does this do?
// We want to use the rdtsc instruction for timing
// It's basically the number of clock cycles on this core since the last RESET
// First up, don't use this for timing! See http://en.wikipedia.org/wiki/Time_Stamp_Counter for why
// The rdtsc is a 64 bit number available from a 32 bit processor
// So it is implemented by putting the low and high parts of the number in two seperate registers
// We define two C variables for these registers (lo and hi)
uint32_t lo, hi;
