If the "main" thread exits it stays around but unlinks itself from the
threads list. Calling TAILQ_NEXT on them is a bad idea and will panic
the kernel. So check the P_WEXIT flag and pretend the thread doesn't
exist if it is set. Also make PT_GET_THREAD_FIRST return the first
thread on the threads list instead of the "main" thread, such that you
can actually keep enumerating the threads in this case.
