Problem with threads programs

["Yuri Kozlov" <kozlov.y@gmail.com>]

Hello.

I just install the Debian Installer etch beta 3 on C3600.
yuray@nmc:~$ cat /proc/cpuinfo
processor       : 0

Installation has been successfull. (except the missing russian fonts
on the console, I have an unsupported graphical card)
Next, I try to compile small program:

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

void *print_message_function( void *ptr );

main()
{
    pthread_t thread1;
    char *message1 = "Thread 1";
    int  iret1;

    iret1 = pthread_create( &thread1, NULL, print_message_function,
(void*) message1);

    pthread_join( thread1, NULL);

    printf("Thread 1 returns: %d\n",iret1);
    exit(0);
}

void *print_message_function( void *ptr )
{
    char *message;
    message = (char *) ptr;
    printf("%s \n", message);
       while(1);
}

yuray@nmc:~$ gcc-4.1 -lpthread thr.c
yuray@nmc:~$ ./a.out
Thread 1

Seems, all is OK.
But:
yuray@nmc:~$ ps -ef|grep a.out
yuray     5426  4914  0 07:23 pts/0    00:00:00 ./a.out
yuray     5427  5426  0 07:23 pts/0    00:00:00 ./a.out
yuray     5428  5427 97 07:23 pts/0    00:00:33 ./a.out

Why?
On x86 this program work as expected and have one process.
