Cluster node view too busy

[rickpayne]

When you have a lot of processes on a node, the cluster view of it gets far too busy to see anything useful. For example:

Along with this, the page changes periodically to show far less processes - ie. some go missing for a few seconds, then reappear. The following screen shot is from the same node a few seconds later - loads of processes have disappeared!

It would be nice to see better names for the processes too...
