It's just another version of the "Broken LSP" that we've been having
problems iwth before. But before, it's only been AV and firewall stuff.

I guess they somehow put a LSP in there to intercept DNS packets or
soemthign. Completely broken design IMHO, but that's a different thing
;-) And they apparantly don't support socket inheritance. The only way
we can work around them breaking the concept of socket inheritance is to
stop using it. Which would mean going multithread instead of
multiprocess, which isn't very likely...

To reiterate the basic point: The broken LSP breaks a fundamental
promise in the sockets API that we absolutely require. The bug is
completely within the LSP.

ISTM that maybe what we have here is a documentation shortcoming.
I'm thinking that our Windows FAQ ought to suggest troubleshooting
socket-related problems by removing LSPs one at a time.
