[Paraview] pvserver does not terminate after gui disconnects

[Utkarsh Ayachit]

Sounds good. Thanks.

If the call stack is same on both processes, it may be that
MPI_Finalize is freezing. Then we can try to track down why
MPI_Finalize would freeze and that would help us get to  the root
cause of the issue.
