As Zebediah noted, this will have a noticable performance impact
(additional server call) for all the socket send and receive operation,
which is very unfortunate, to say the least. Is it maybe possible to
introduce something like a shared memory section to store the dynamic
state for the state that can't be cached locally (the question is also
for Zebediah)? Maybe it will be easier to do once the winsock IO move to
ntdll is complete?
