too many update information requests
As I am adding logging support to ParaView, simple tasks can cause too many update-pipeline-information requests. While these are often no-ops, they can slow the UI down when in client-server configurations. We should look into it.
Here's the log on simply changing the Clip plane and hitting Apply.
