I just noticed that this is also what Eric's original mail was about, so
I suppose I just second his concern. We had the issue in ice4j and we
basically just had to implement and tune it in a way that would work
against other common ICE impls.


Text that specifies exactly how this is to be done would have been most
helpful.
