    Sorry I've been mostly silent recently.  It is great to know that their 
    are folks like Alan to help others when I cannot.
    I am very busy now with preparations for the annual Supercomputing 
    conference to be held in two week.
    Once that is past I'll need to catch up on a backlog of other work.
    So, I doubt that I'll have much time until early December to look at the 
    2.6.31 problems.
    I will try to find time sooner, but wanted to make sure nobody had 
    unrealistic expectations.
