RE: Interesting article...

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

Steve,

Just a quit reply to go with my last.  Didn't realize you were giving a link to 
the /. discussion that took place right after the system crash.  

I was thinking you were referring to the /. discussion of the article itself.

You're correct, that the link you posted has some good info.  Haven't run 
across any posts saying that the bug ( or more importantly its affects) were 
know.  But I'm not through them all yet.
