No, I won't spend "a lot more" time trying to decipher the supposedly hidden meaning of your post and invest the time more wisely by making MSM more useful. The link I added seems quite clear to me and anyone interested can make himself his own opinion by opening it. You did not bother bringing an argumentation disproving my claim, so I will simply keep it. As you also didn't address the more important technical part (multiple TU) of my answer, I will consider it accepted.
I want to apologize for the harsh language I used and the uncharacteristic loss of patience I displayed. I also wanted to let you know that I of course accept your explanation as not doing it would be suspecting you of being dishonest, which I have not been doing at any time. I admit honestly failing to understand what is the impossibility you claim, thus the confusion. I think there is no interest right now for a technical discussion but for the record, I do not accept any impossibility of any sort and the next version of MSM will include a precise example of a multi-TU fsm to illustrate my claim. I wish all of you a happy, successful new year. Christophe
