Bill,

Sure.

Well, I would say that "fixed" is a matter of opinion.   Are you saying that "fixed" means that the operating system does not lock up tighter than a drum?  The routing table in the OS is very messed up.  I will direct a question to Microsoft on this as well.

Sam Bowne had done a bit of research on this issue, including characterizing the behavior on multiple systems as well as confirming that Microsoft had mostly fixed the problem with patches in 2013.
