[Paraview] running paraview in parallel

[burlen]

Also be aware that there is a bug in ParaView, where if the server 
startup command doesn't return for some reason, ssh turns into an orphan 
process and will not relinquish the ports it used, preventing any 
further use of those ports.

http://www.paraview.org/Bug/view.php?id=10283

I did submit a patch to fix it but it has yet to be applied.
