You are probably right, its been quite a while, and there were other factors that have effected my perception. The driver just for the engine didn't require the stack portion that Prafulla did, although we need something using the thing :) Not sure what other implementation you are thinking of. Linux has it of course. I'd be glad to resurrect the code and get on with it in any case. Jack
