Rick, thanks for shedding more light on the subject. Actually, I wasn't
asking the question as I've been relatively worry free about it for some
time - unless a customer gets overly concerned about it.

I think Joe, and many others talk well about what it looks like and how it
compares with other such findings as hole wall pull away. I've been through
the well written 600 many times and can't even find anything concerning it.
For me, Section 3.1, and in particular 3.1.1's figure showing the thermal
and laminate evaluation zones and what falls out of it, pretty much tells
the whole story.

Earl
