[ipv6hackers] Windows 7/2008 R2 Improved Resilliency to IPv6 Floods

it is vulnerable to RA flooding (especially routing entries with small
lifetimes), but not resulting BSOD or similar. The CPU stays at 100%
until the flooding is over, then resumes normal operation.

Same problem as in Linux, FreeBSD, OS X, however on those weird things
can happen, e.g. IPv6 stack breaks (no connectivity possible) or system
hicups.

So at the moment Windows is in a better state compared to other OS when
it comes to RA flooding.

Greets,
Marc
