IPC also includes a set of six sys_mq_* call, but I believe that everyone already has those as they are not covered by sys_ipc. For y2038 compatibility, we will likely add a new variant of semtimedop that takes a 64-bit timespec. While the argument passed there is a relative time that will never need to be longer than 68 years, we need to accommodate user space that defines timespec in a sane way, and converting the argument in libc would be awkward.
