* @param req can be a relative or absolute time, depending on `flags`
* @param rem will be updated with the unslept time only when `flags`
* is zero, otherwise `rem` is ignored; when this call completes,
* that means `rem` will be set to `{0, 0}`, and shall only have
* something else when -1 is returned with `EINTR`, which means
* there was a signal delivery that happened mid-sleep and `rem`
* reflects (poorly) how much remaining time was left over, in
* case the caller wishes to retry the sleep operation, noting
* this isn't recommended since relative timestamps can drift
* @param rem shall be updated with the remainder of unslept time when
* (1) it's non-null; (2) `flags` is 0; and (3) -1 w/ `EINTR` is
* returned; if this function returns 0 then `rem` is undefined;
* if flags is `TIMER_ABSTIME` then `rem` is ignored
* @return 0 on success, or -1 w/ errno
* @raise EINTR when a signal got delivered while we were waiting
* @raise ENOTSUP if `clock` is known but we can't use it here
