State-Changed-Why:
    Confirmed. Martin Buchholz send a couple of optimization
    reports a couple of weeks ago, in which I also documented
    this. Note that allocating too much stack space is not 
    wrong, it's just a waste. And it reduces locality of data
    with the usual problems with cache sizes.
