On my computer the pthread test programs fail because the task thread completes
before the detach.  I have a dual PIII 800 Mhz box.

symptom:

pthread_detach_status = 3
strerror(3) = No such process

work around:

I added busy work to each test program in configure:

static void *task(p)
    void *p
{
      /* busy work so thread doesn't complete before detach */
      int i = 100000 ;
      while (i--) {
        int j = i / 3 ;
      }

      return (void *) (p == NULL) ;
}

Please upgrade configure with this work around or whatever you deem
appropriate.

Thank you.
