A 4.1 server must notify a client that has had any state revoked using
the SEQ4_STATUS_RECALLABLE_STATE_REVOKED flag. The client can figure
out exactly which state is the problem using CHECK_STATEID and then free
it using FREE_STATEID. The status flag will be unset once all such
revoked stateids are freed.
Our server's only recallable state is delegations. So we keep with each
4.1 client a list of delegations that have timed out and been recalled,
but haven't yet been freed by FREE_STATEID.
