OK, D&T again went into the mode where he posts some strawman arguments then deletes them. I'll have to paraphrase:
Mining ASICs are nearly 100% deterministic, more precisely (100% - allowable fault rate). The problem we are facing is that thus far only "false positive" faults were measured by the mining software. Maybe the threat of the block withholding attacks will force everyone to cooperate on the measurement of the "false negative" fault rate.
Hopefully vendors will cease to obfuscate like this:
It won't work. Our miners for example don't check all nonce range, and a lot of cgminer generated jobs get dropped. Also we use ntime-rolling differently from other pools. It's impossible to know what the miner will generate from stratum template.
or like eldentyrell did with the timebomb in his Tricone Mining bitstream for Xilinx Spartans.
