User threads can use either wait() (for processes) or
thr_join()/pthread_join() (for threads). Normally in a multiprogrammed
environment this is how you would do it. (Kernel threads are a bit
special, so I'm not 100% sure here. But the new threading model is 1:1
so unless the threads are somehow created without user context (such as
a kernel taskq thread) it should be good enough for most uses.
I would look at the implementation of these functions to see if you can
figure out how to do it for kernel threads without any user context, if
you really need that.
