Probably not that useful in that it was an old QT, no longer compiles. More importantly I have a tiny OS that doesn't have real threads (code had to run on 8k)

Probably not that useful in that it was an old QT, no longer compiles. More importantly I have a tiny OS that doesn't have real threads (code had to run on 8k), I port it all over it simply consists of a timer queue, and one stack - threadlets are a queue entry with a data pointer - running 14k instances of this tiny OS in one simulator is pretty easy (you still just have one timer queue ....) - so you can see it's all pretty dependant on the uOS The only hard part is making packet delivery not O(N2)
