Very nice and fast Xiao Feng :-) I read through your first submission and had a couple of thoughts on how this could progress. Is it that to hook up the two seperately managed spaces, some of the policies ( eg., promote everything and have an upper limit on pause time ) need become implicit? Or can we build in some structures for policy support later, eg., if we want to set aside a seperate creation space, and provide some concept of age ...maybe confine the copying implementation to a smaller aging space.... I know that we made some assumptions upfront but I am not sure how well two generations will work for the real apps( not Spec ) eg., where pause is critical. We may want to keep policies orthogonal to this so that we are flexible. Thanks, Rana
