  I have written a simple program on my PC using PVM 3.4 beta4 and I can't
understand its strange behaviour. The program is very simple. It just
creates a new context, sets it and tries to join a certain group. It
looks as follows:

main( ... ) {

  int mycontext=pvm_newcontext();

  pvm_setcontext(mycontext);

  pvm_joingroup("kkk");


  pvm_exit();

}

After starting this process, it doesn't exit. It happens every other run.
If we move pvm_joingroup before setting a new context or remove it, it'll
work. The situation is similar when replacing pvm_joingroup with
pvm_bcast, for instance.
  Does anyone know this problem? Is it the problem of PVM?
