>Description:

	Calling pthread_exit() from only (main) thread 
	does not cause process to exit.

>How-To-Repeat:

#include <pthread.h>

int main(int argc, char** argv)
{
        pthread_exit( NULL );

        /* not reachable */
        return -2;
}

	cc -o threadtest threadtest.c -pthread
	./threadtest; echo $status

Process will not exit until interrupted/killed.
Top(1) shows process in 'select'.

>Fix:

Woraround: Keep track of number of active threads and
have last thread exit with exit() instead of phtread_exit().
