[Paraview] vtkSMCollaborationManager::FollowUser(id) doesn't update view

[Utkarsh Ayachit]

ProcessEvents() doesn't poll the server. It only "select"s on the
socket to see if the server sent any new messages to the client.

> One more question out of curiosity: isn't it quite ineffient, if clients
> continuously invoke vtkNetworkAccessManager::ProcessEvents´()? For smooth
> interaction this has to happen at least 10 times per second, which causes a
> lot of network traffic by polling the server again and again,  especially if
> more than one client connects to the same server.
> Isn't it possible to react on incoming server events by registering a
> callback that does the same server event processing only when a new event
> has occurred? I mean, all of VTK and ParaView is event based, why not the
> server message processing?
