   I set the timing to 16 clocks which is about 64 (or more) instructions.   
   Did not want to go much over 1% the number of instructions executed.   
   Not every instruction inserts a poll, so sometimes a poll is lacking.   
   IDK how well it will work. Making it an instruction means it might also   
   be used by software.
