Change Details

Linux has more tolerant checks of cpuset size, the minimum cpuset_t size that the Linux kernel permits from a user-space is a number of active cpus / NBBY, the maximum cpuset_t size is not limited. To match the behavior of the Linux we will internally operate with the native cpuset_t, but for user space we will expose cpuset_t in the range from min(len, cpus * NBBY) to min(len, sizeof(cpuset_t)).

Also cache thread tid to avoid ref to an unlocked thread.
