Keith - I think Iris is going to get back to you shortly on this. One
thing that needs to be figured out here is the implication for any
existing applications that might depend on the current (broken)
behavior. Unfortunately we have to worry about such things. In this
case, if there is existing code that (perhaps unknowingly) depends on
the current behavior then we might break it by a reset throwing an
invalid mark exception in cases where it isn't thrown today. In the past
we've had to introduce system properties to allow for "bug
compatibility" with previous releases. I'm not saying we need it here
but we need to think about it.
