The point is that if the server won't allow them to issue read or write system calls, then there are 2 options available to them:
1. hang until someone renews their ticket 2. get an error which means crash, since most (all?) applications aren't written according to the non-posix assumption that read and write can return EACCES/EKEYEXPIRED errors.
