I wasn't clear about this.

I don't think the probability will change at all under 7.0.  There is one 
large address space (up to 14 megabytes) and everything lives there.  
There is no protection at all.

The comment about low memory was simply repreating what was stated at the 
Developer's Conference.  If protection was done between application heaps 
(which it isn't), it would only be a red herring since the system heap and 
low memory is shared.  The thought was that it was better to come up with 
a total solution in some future system, rather than give users a false 
sense of confidence.
