Rather than having a per thread lock, Solaris uses the lock for the
current container that a thread is associated with (cpu, run queue,
sleep queue, etc.) to serialize thread updates. I think this is probably
the best approach. A per proess spin lock would not scale well for large
multi-threaded apps.
