No,i'm not BSZ/NST ..sorry 
You are right,this idea need some refinement. Which instruction has two write cycles? I think,only far calls are pushing two bytes onto the stack...and this should happen too,when an interrupts is served.
Unfortunately this is a long chance,dma coming while a far call is executed..maybe we must wait for minutes or hours after the button is pressed..this useless on this way.
What,if we are watching only two writing cycle,this should be the last two cycle of an instruction,a new fetch cycle is coming now..?
