Hello,

I am using pth-1.3.7 (GNU Portable Thread library) and exit() won't
exit. I have a small test program that has a main like this:

int main(int argc, char *argv[])
{ 
  pthread_name_test();

  cout << "Program will now exit..." << endl;
  exit(EXIT_SUCCESS);

  return (0);
}

The basic purpose of the program seems to work (it does some testing with
POSIX threads) and pthread_name_test() returns control to main() for
execution. Executing the program produces output like this:

  [... deleted for space ...]
  
  pthread_name_test() end
  Program will now exit...


At this point the program does not exit. Running top on the system shows
that my process is using up about 95% of the CPU.

Using gdb I can attach to the process and it looks like the pth package
has installed an exit handler as it is currently stuck in
pth_mutex_release():

Has anyone else using the pth package seen this type of behaviour before?
In case it matters, this is on a 1.5_ALPHA2/i386 system:

  palomino:{root}# uname -a
